Electronic ceramics, as an important new strategic material, is the core material of passive electronic components and an important technological frontier in the field of electronic information technology
.
With the increasingly integrated, intelligent and miniaturized electronic information technology, passive electronic components have increasingly become the bottleneck of the development of electronic component technology, and the strategic position of electronic ceramic materials and their preparation and processing technology has become increasingly prominent
.
China's electronic ceramic materials and components have formed a good industrial technology foundation, but the competitiveness in high-end materials and components is still insufficient, and some key material technologies, process technologies and equipment technologies are subject to others
.
Research believes that: in the face of the new situation, it is urgent to increase R&D investment, straighten out the system and mechanism, and strengthen the independent controllability and independent innovation of the industrial chain
.
? 1.
Introduction? Electronic ceramics are the core material of passive electronic components and an important material basis for electronic information technology
.
In recent years, as electronic information technology has become increasingly integrated, thinner, intelligent and miniaturized, active devices and integrated circuits based on semiconductor technology have developed rapidly, and passive electronic components have increasingly become the development of electronic component technology.
Therefore, electronic ceramic materials and their preparation and processing technology have increasingly become one of the important core technologies that restrict the development of electronic information technology
.
? China is a large country of passive electronic components.
From the perspective of product output, passive components account for more than 40% of the world's output; but it is not a strong country.
The component output value is less than a quarter of the global output value, and high-end components rely heavily on imports
.
Electronic ceramic materials and technology are one of the important factors restricting the development of high-end components
.
Judging the development status of domestic and foreign electronic ceramic materials and component technology from a strategic perspective, and analyzing the problems and countermeasures in related fields in China are of great significance for promoting the development of China's high-end electronic components industry
.
Second, the current status and trends of the development of the international electronic ceramic industry technology? From the perspective of the global electronic ceramic industry technology level, Japan and the United States are in a leading position in the world
.
Among them, Japan has a dominant position in the world electronic ceramic market by virtue of its ultra-large-scale production and advanced preparation technology, occupying more than 50% of the world electronic ceramic market[2]
.
The United States is strong in basic research and new material development.
It focuses on cutting-edge products and applications in the military field, such as underwater acoustics, electro-optics, optoelectronics, infrared technology, and semiconductor packaging
.
In addition, South Korea has developed rapidly in the field of electronic ceramics and has attracted attention
.
? (1) Multilayer Ceramic Capacitor (MLCC) Industry? The main application field of electronic ceramics is passive electronic components
.
MLCC is one of the most used passive components at present.
It is mainly used in the oscillation, coupling, and filter bypass circuits of various electronic complete machines.
Its application fields involve automatic meters, digital home appliances, automotive electrical appliances, communications, computers and other industries.

.
MLCC occupies an increasingly important position in the international electronics manufacturing industry, especially with the increasing demand of consumer electronics, communications, computers, networks, automobiles, industrial and defense end customers, the global market has reached tens of billions of dollars, and The annual growth rate is 10%~15%
.
Since 2017, due to supply and demand, MLCC products have experienced several price increases
.
Japan is a major producer of MLCC, Japan’s Murata (nuRata), Kyocera Corporation (KYOCERA), Taiyo Yuden Co.
, Ltd.
(TAIYO YUDEN), TDK-EPC, South Korea’s Samsung Electric Co.
, Ltd.
(SEMCO) and China’s Taiwanese Huaxin Technology Co.
, Ltd.
and Yageo Co.
, Ltd.
are all world-renowned MLCC manufacturers
.
The mainstream development trend of MLCC is miniaturization, large capacity, thin layer, base metalization, and high reliability.
Among them, the base metalization technology of internal electrodes has developed most rapidly in recent years.
The use of base metal internal electrodes is the most important way to reduce the cost of MLCC.
An effective way, and the key technology to realize base metalization is to develop high-performance anti-reduction barium titanate porcelain
.
Japan has completed the development of this technology at the beginning of the 21st century, and has always maintained the world's leading position.
At present, all its large-capacity MLCCs have realized base metalization
.
The miniaturization of size has always been the main trend in the development of MLCC.
With the increasing development of electronic equipment in the direction of miniaturization and portability, product upgrades are rapid, and there is a strong demand for miniaturized products, as shown in Figure 1.

.
The basic material technology for miniaturization of components is the thinning technology of the ceramic dielectric layer
.
At present, Japanese companies are in a leading position in the world, and the thickness of their MLCC monolayers has reached 1 μm.
Among them, the research and development level of the top Japanese Murata and Taiyo Yuden Co.
, Ltd.
has reached 0.
3 μm
.
The basis of dielectric thinning is the miniaturization of dielectric materials
.
While the thickness of the single layer of the large-capacity thin-layered MLCC component is gradually reduced, in order to ensure the reliability of the component, barium titanate is the main crystal phase of the MLCC ceramic medium, and its particle size needs to be further refined from 200 to 300 nm to 80 ~150 nm
.
The future development trend is to prepare barium titanate with a particle size of 150 nm as the main crystalline phase material of the MLCC dielectric layer
.
? Figure 1 Changes in the market share of MLCCs of various sizes in recent years? (2) Chip inductor industry? Chip inductors are another type of passive electronic components that are used in large quantities.
They are three types of passive chip components.
The most complex type of technology, its core material is magnetic ceramics (ferrite)
.
At present, the total demand for chip inductors in the world is about 1,000 billion, with an annual growth rate of more than 10%
.
In the development and production of chip inductors, Japan's production output accounts for about 70% of the world's total
.
Among them, TDK-EPC, Murata and Taiyo Yuden Co.
, Ltd.
have always mastered cutting-edge technologies in this field
.
According to statistics from the Industry Information Network (IEK), in the global inductor market, the combined output of TDK-EPC, Taiyo Yuden Co.
, Ltd.
and Murata accounts for about 60% of the global market
.
The main trends in the development of chip inductors include small size, high inductance, high power, high frequency, high stability, and high precision
.
The core of its technology is soft ferrite and dielectric materials with low-temperature sintering characteristics
.
? (3) High-performance piezoelectric ceramic industry? Piezoelectric ceramics are an important energy conversion material with excellent electromechanical coupling performance.
They are widely used in electronic information, electromechanical energy conversion, automatic control, microelectromechanical systems, and biomedical instruments.

.
In order to adapt to new application requirements, piezoelectric devices are developing in the direction of multilayer, chip and miniaturization
.
In recent years, some new piezoelectric devices such as multilayer piezoelectric transformers, multilayer piezoelectric actuators, and chip piezoelectric frequency devices have been continuously developed and are widely used in electrical, electromechanical, and electronic fields
.
At the same time, in terms of new materials, the development of lead-free piezoelectric ceramics has made a major breakthrough, which may make it possible for lead-free piezoelectric ceramics to replace lead zirconate titanate (PZT)-based piezoelectric ceramics in many fields, and promote green electronics.
Product upgrades
.
In addition, the application of piezoelectric materials in the next generation of energy technology has begun to emerge
.
In the past ten years, with the development of wireless and low-power electronic devices, the research and development of miniature energy harvesting technology using piezoelectric ceramics has been highly valued by governments, institutions and enterprises in various countries
.
? (4) Microwave dielectric ceramic industry? Microwave dielectric ceramic is the cornerstone of wireless communication devices
.
It is widely used in mobile communication, navigation, global satellite positioning system, satellite communication, radar, telemetry, Bluetooth technology and wireless local area network (WLAN) [7]
.
Components such as filters, resonators, and oscillators composed of microwave dielectric ceramics are widely used in 5G networks, and their quality largely determines the final performance, size limit and cost of microwave communication products
.
Microwave electromagnetic medium materials with low loss, high stability and modulatable are currently the core technology in the world
.
Microwave dielectric ceramic materials have formed a fierce competition in the United States, Japan, Europe and other countries and regions in the early stages of development, but then Japan has gradually been in a clear dominant position
.
With the rapid development of third-generation mobile communications and data microwave communications, the United States, Japan, and Europe have all made strategic adjustments to the development of this high-tech field
.
Judging from the recent development trend, the United States has made nonlinear microwave dielectric ceramics and high dielectric constant microwave dielectric ceramic material technology as a strategic focus, Europe focuses on materials for fixed frequency resonators, while Japan has relied on its industrial advantages to vigorously promote microwave dielectric Standardization and high quality of ceramics
.
At present, the production level of microwave dielectric materials and devices is highest in Japan's Murata, Kyocera Corporation, TDK-EPC Corporation, and US Trans-Tech Corporation
.
? (5) Semiconductor ceramic industry? Semiconductor ceramics are a kind of information functional ceramic materials that can convert physical quantities such as moisture, air, force, heat, sound, light, and electricity into electrical signals.
They are widely used and are the mainstay of the Internet of Things technology.
Basic materials, such as positive temperature coefficient thermistor (PTC), negative temperature coefficient thermistor (NTC) and varistor, as well as gas and humidity sensors
.
The output and output value of heat-sensitive ceramics and pressure-sensitive ceramics are the highest among semiconductor ceramic materials
.
Internationally, the thermistor ceramic materials and devices are based on Japanese Murata, Shibaura Electronics Co.
, Ltd.
, Mitsubishi Group (Mitsubishi), TDK-EPC, Ishizuka Electronics Co.
, Ltd.
(Ishizuka), US VISHAY (VISHAY), Germany EPCOS (EPCOS) and other companies have the most advanced technology and the largest output.
Their annual output accounts for about 60% to 80% of the world's total.
Their products are of good quality and high prices
.
In recent years, foreign ceramic semiconductor devices are developing in the direction of high performance, high reliability, high precision, multilayer chip and scale
.
At present, some large foreign companies have successively launched some chip semiconductor ceramic devices based on multilayer ceramic technology, which have become high-end products in the field of sensitive devices
.
?? Third, the development status of China's electronic ceramic materials and components? China is a big country of electronic components, the output of a variety of electronic ceramic products ranks first in the world, and has formed a number of internationally competitive component product production bases , And has the world’s largest application market
.
However, the current high-end electronic ceramic material market is mainly monopolized by Japanese companies.
A small part of the domestically produced materials is used in high-end component products, and most of them are used in low-end component products; domestic high-level scientific research results have encountered problems in the conversion process.
Bottlenecks in raw materials, production equipment, stability, etc.
, account for a relatively low market share
.
? In terms of industrial technology, my country's electronic ceramics and its component products production base has formed a considerable scale, and has an internationally advanced production level
.
Among them, Fenghua High-tech Co.
, Ltd.
is one of the few comprehensive enterprises in the world that integrates the “three-in-one” industrial system of electronic components, electronic materials, and electronic special equipment; Sunlord Electronics Co.
, Ltd.
LTCC products have obvious international competitive advantages; Chaozhou Sanhuan (Group) Co.
, Ltd.
, Shenzhen Yuyang Technology Development Co.
, Ltd.
and other leading enterprises in the ceramic electronic component industry also have a certain international influence It is supported by a series of national R&D plans
.
Led by Tsinghua University and Fenghua High-tech Co.
, Ltd.
, the electronic technology innovation strategic alliance formed by 20 large and medium-sized enterprises, research institutions, and universities is important for promoting the research, development and industry of functional ceramic chip components and passive integrated industrial ceramic materials.
Combination played an important role
.
? (1) MLCC industry? China's MLCC industry has a relatively large scale and has formed a group of large internationally competitive companies represented by Fenghua High-tech Co.
, Ltd.
and Shenzhen Yuyang Technology Development Co.
, Ltd.
, and are in international competition.
Take a place
.
However, as the world’s top MLCC manufacturers such as Japan’s Taiyo Yuden Co.
, Ltd.
, Murata, Kyocera Co.
, Ltd.
, TDK-EPC and South Korea’s Samsung Electro-Mechanics Co.
, Ltd.
and other large companies have successively established manufacturing bases in mainland China, they have transferred their production capacity to China.
The mainland has shifted.
At present, more than half of the domestic MLCC production is occupied by foreign capital and joint ventures
.
At the same time, high-end MLCC products in the domestic market mainly rely on imports
.
Due to the lack of independent intellectual property rights and advanced process equipment, high-performance ceramic powder, electrode slurry, and advanced production equipment are largely dependent on foreign manufacturers
.
In terms of market conditions, MLCC consumption is mainly concentrated in Asia, accounting for 75% of global MLCC consumption, while China accounts for more than half
.
With the continuous expansion of the complete machine manufacturing industry such as mobile communication products, the demand for MLCC products in China is still growing rapidly
.
? (2) Chip inductor industry? my country began to develop and produce chip inductors and related materials in the early 1990s
.
At present, an inductor industry that takes both traditional and new products into consideration, has a considerable economic scale, and occupies a certain position in the international market has basically been established, and its output accounts for about 20% of the world's total output
.
Among them, Shenzhen Sunlord Electronics Co.
, Ltd.
has taken a place in the international competition by virtue of its technological advantages in materials and processes
.
However, the current domestic chip inductor manufacturers still have some problems.
Most of their products are for consumer electronics.
Such basic components used in the communications and automotive electronics fields are mainly monopolized by companies in Japan, South Korea, and Taiwan
.
At the same time, the price war in the low-end market has caused the profit margins of domestic chip inductor manufacturers to shrink
.
At present, the global market's demand for chip inductors is constantly increasing, and the market structure is also constantly changing, especially the growth rate of the mobile/wireless communication field is amazing
.
Most of the manufacturers of mobile communication products represented by mobile phones are in China, and most of the chip inductors used in mobile communication are currently supplied by foreign countries
.
Computers and automotive electronics are also areas where the domestic demand for high-end chip inductor products is growing rapidly
.
For a period of time in the future, China's market gap in high-end chip inductors will be quite large
.
? (3) High-performance piezoelectric ceramic industry? In terms of high-performance piezoelectric ceramics and components, there are a large number of piezoelectric ceramic companies in China, but most of them are small and medium-sized enterprises, and the product structure is mainly low-end products
.
Although in the past few decades, the research and development of piezoelectric ceramics in China has made a number of technological achievements with independent intellectual property rights
.
However, judging from the current overall situation of the industry, its market competitiveness and industrial technology level need to be improved urgently, and the product structure needs to be upgraded
.
With the rapid development of information technology, new energy technology, biomedicine and aerospace technology, the application market of some new piezoelectric ceramic devices will rise rapidly and become the main market of piezoelectric ceramic devices
.
? (4) Microwave dielectric ceramic industry? In terms of microwave dielectric ceramic materials, the research on microwave electromagnetic medium in my country started earlier, basically synchronized with developed countries.
In the early stage, research, development and production mainly focused on the needs of key microwave devices in the defense and military industry.

.
In the past ten years, several enterprises of a certain scale have been formed, such as Wuhan Fangu Electronics Co.
, Ltd.
, Jiali Electronics Co.
, Ltd.
, Dafu Technology Co.
, Ltd.
, Shenzhen Sunlord Electronics Co.
, Ltd.
, and Jiangsu Canqin Technology Co.
, Ltd.
and so on
.
However, these companies still have a big gap in technology level, product variety and production scale compared with internationally well-known large companies
.
The rapid rise of wireless information technology represented by the fifth-generation mobile communication (5G), wireless Internet, wireless sensor network, and satellite communication and positioning systems has put forward higher requirements for high-performance microwave devices, and there is a lot of room for development.

.
? (5) Semiconductor ceramic industry? At present, most domestic semiconductor ceramic and related sensitive device manufacturers were established in the 1990s, with foreign-funded enterprises and private enterprises as the main body
.
Foreign-funded enterprises have rapidly established production bases in the domestic market through sole proprietorship or joint ventures.
They have significant technical advantages, excellent product performance, and large export volumes, occupying a dominant position in the domestic high-end market
.
From a technical point of view, the production technology of private enterprises is backward, and there are still major deficiencies in raw materials, production equipment, testing equipment, quality control, etc.
, resulting in a single domestic product line, and the product structure is mainly low-end, unable to meet the needs of the high-end market.
Demand
.
From the perspective of future demand, the rapid development of the Internet of Things and sensor networks will bring about explosive growth in the demand for semiconductor ceramic sensors in China, and there will be more room for development in the future
.
? "Four.
Analysis of major technical requirements for electronic ceramic materials? With the further development of electronic information products in the direction of broadband, miniaturization, integration, wireless/mobile, and green, electronic ceramic components are becoming more multifunctional and multi-layered.
The integration of multi-layer components and chip components has become the mainstream of development.
These new trends have put forward a series of new requirements for electronic ceramic materials, such as the fine crystallization of materials, the diversification of material functions, The high frequency and low loss of electromagnetic properties, etc.

The related material technology has increasingly become a bottleneck technology that restricts the development of information technology
.
In the next few years, the key technical issues that need to be resolved in the development of electronic ceramic materials include the following aspects
.
? (1) New electronic ceramic materials and their key technologies for electronic information systems that meet the miniaturization/miniaturization of electronic components
.
The preparation technology, thin film forming process nanocrystalline ceramic materials; suitable for low loss microwave dielectric ceramics critical components like low-energy wireless / mobile information systems
.
? (2) New electronic ceramic materials adapted to the characteristic frequency of the new generation of mobile communication technology
.
With the development of 5G/6G technology, the communication frequency band is gradually advancing from microwave to millimeter wave, and the demand for new electronic ceramics that adapt to higher frequency bands, especially ceramic dielectric materials, will increase sharply, and the development of related materials and devices is imminent
.
? (3) New electronic ceramic materials for passive component integration and passive-active integration and modularization
.
Passive integration technology based on LTCC technology will have more room for development, and various functional ceramic materials compatible with this technology and their co-firing technology are a technical bottleneck that needs to be overcome urgently
.
? (4) New functional electronic ceramic materials for the multi-functionalization of electronic information systems
.
New multifunctional ceramic material systems with electrical, magnetic, optical, thermal coupling behavior and super-normal electromagnetic properties, as well as new information functional ceramic materials with stability and excellent service behavior when working in complex external fields or extreme environmental conditions
.
? (5) Other technical fields also put forward new demands on electronic ceramic materials
.
In terms of energy materials, the further development of solid fuel cells, solar cells and semiconductor lighting technologies depends on breakthroughs in electronic ceramic materials and their preparation technology; with the rise of the Internet of Things and sensor networks, a wide variety of sensors with different functions are required.
The emergence of new sensitive ceramic materials with more and higher performance
.
Five, the main problems facing the development of China's electronic ceramic industry? The current main problems facing China in the development of electronic ceramics and its components industry include the following points
.
? (1) The degree of social attention is seriously insufficient? The important position of electronic ceramic materials in electronic information technology is second only to semiconductors
.
However, compared with semiconductor technology, the attention of all sectors of society is seriously insufficient
.
As Murata (China) President Maruyama Hideyoshi pointed out: China has support for chips and semiconductors in national policy, but there is no great support for components, so Chinese component companies are more of their own development
.
Due to insufficient social investment, companies lack a mechanism to attract high-level talents, their R&D capabilities are weak, and R&D funds are lacking, making it difficult to adapt to the ever-changing R&D needs
.
(2) The research results transformation mechanism needs to be improved? The research and development work of domestic electronic ceramic materials is scattered in a small number of universities, research institutes and a small number of large enterprises.
Among the universities and research institutes, they belong to different fields of materials and components.
There are big differences in the focus, and they are out of touch with each other, and there is a lack of systematic research on the integration of materials, processes, and components
.
The transformation of R&D achievements to industrialization is not timely and inadequate
.
Institutions of higher learning, research institutes and enterprises are separated from each other, communication and collaboration are insufficient, and there is no effective mechanism that can transform the results in a timely and effective manner and realize the combination of "production, study and research"
.
The research results of universities and research institutes often stay in the laboratory work stage, and there is no product test and mass production verification, and the research and development in the enterprise is often not deep enough due to the lack of experimental analysis equipment
.
? (3) The domestic industrial chain is not fully supporting independent innovation? Electronic ceramic materials are located in the upper and middle reaches of the industrial chain, with raw materials at the front end and components at the back end
.
As the component process equipment and technical standards are mainly from abroad, domestic raw material products still have a gap with foreign products in terms of stability and consistency, which restricts the large-scale application of domestic electronic ceramic materials in component products
.
In particular, some original materials, due to the lack of compatibility with existing component technologies, are difficult to obtain applications, making it difficult for domestic electronic ceramic materials and components to enter the leading position in the industry
.
? (4) The level of large-scale production process and equipment needs to be improved? At present, domestic high-end electronic ceramic materials and components are still mainly imported
.
Due to the rapid technological upgrading, it is difficult for advanced technology to enter the country, which makes it difficult for the level of large-scale production to be in a leading position in the world
.
Take the leading enterprises in the domestic ceramic passive component industry as an example.
Fenghua High-tech Co.
, Ltd.
, Sunlord Electronics Co.
, Ltd.
and Yuyang Technology Development Co.
, Ltd.
are domestic backbone enterprises mainly engaged in the production of chip components, but their high-end the level of product technology and world-renowned enterprises TDK-EPC, Taiyo Yuden Co.
, Ltd.
and so there is a big gap
.
