Jingxing Technology realized the mass production of fiber-grade silicon tetrachloride

Recently, Hubei Jingxing Technology Company broke through technical barriers and purified the waste silicon tetrachloride generated during the production of polysilicon to make high-purity fiber-grade silicon tetrachloride, realizing the mass production of fiber-optic grade silicon tetrachloride and breaking the monopoly
of international imports.

In the information age, optical fiber communication has become the first choice
due to large conduction capacity, high efficiency and small loss.
Nowadays, optical fiber communication materials mainly use high-transparency optical fiber preforms, and silicon tetrachloride is the main raw material
for the production of preforms.
The domestic production of high-purity silicon tetrachloride optical fiber preforms is very small, and more than 80% rely on imports
.

For polysilicon production, silicon tetrachloride is a by-product
.
Every one polysilicon product produced will produce more than 10 highly corrosive, toxic and harmful by-products silicon tetrachloride waste liquid, and its treatment cost is about
600 yuan / ton.
According to industry insiders, previously, the purification of silicon tetrachloride from the waste liquid remained in the laboratory, the process was complex, and it was protected by foreign technology, and mass production
had not been achieved in China.

At the end of 2012, the technical team of Jingxing Company successfully developed and built an optical fiber grade silicon tetrachloride purification device
.
After debugging and operation, the company successfully purified high-purity silicon tetrachloride from the waste liquid, which can meet the raw material requirements for the production of high-quality optical fiber preforms, and has become the first domestic mass production enterprise, with a monthly production capacity of 2,000 tons, filling the gap in the domestic market and breaking the barriers
of international imports in one fell swoop.

China has the world's largest fixed-line communication network, mobile subscriber network and Internet user base
.
At present, 4G networks are gradually covered, and the demand for optical fiber and cable in the "Broadband China" strategy is still very large
.
The mass production of fiber-optic grade silicon tetrachloride by Crystal Star Technology can effectively solve the problem of China's optical fiber communication raw materials being restricted by foreign countries, and promote the development of strategic emerging industries such as China's communication industry, triple-network integration, and Internet of
Things.
