For the first time, I prepared ultra-high purity rare earth modified alumina

Reporter 25 from Shanghai Jiaotou University Baotou Materials Research Institute Saifu New Materials Co. , Ltd. learned that by the Shanghai Jiaoda University School of Materials Science and Engineering research and development team independently developed rare earth modified high-purity sapphire raw materials pilot project officially put into production, the production line for the first time output 5N (purity greater than 99.999%) high purity alumina products. High-purity alumina is a high-end product of aluminum industry, is also the main raw material of artificial sapphire, the new project to make up for the international rare earth high-purity aluminum preparation technology gap, will also make high-purity aluminum industry chain and artificial sapphire industry chain to achieve a full line.
the research and development team has the first set of ultra-high-purity aluminum purification process and equipment with fully independent intellectual property rights to
china
. Team leader Professor Zhang Chao said that the new technology will be high-purity alumina purification process and rare earth new material preparation technology perfectly integrated, after adding rare earths, the product not only in toughness has been greatly improved, in color brightness and hardness has also achieved a great improvement, can now prepare 6N ultra-high purity aluminum ingots, and 5N ultra-high purity aluminum ingots for large-scale production, for China's ultra-high purity alumina raw materials mass production has laid a solid foundation.
It is understood that high purity aluminum hydrolytic preparation of purity of more than 5N of high purity alumina, is the production of LED substrate sapphire single wafers of the main raw materials, more than 90% of the world's LED enterprises are using sapphire as a substrate material. In addition, high-purity alumina is also widely used in lithium battery diaphragm materials, high-end phosphor, catalysts, semiconductor ceramics and so on.
Pan Tianlong, general manager of Saifu New Materials Co., Ltd., said: "This new product was not on the market before, our ultra-high purity aluminum ingots to fill the gap in this production technology, our upstream is the aluminum industry chain, downstream is the industrial chain of artificial sapphire crystals, this new product for the first time to achieve the seamless docking of China's two industrial chains." Next, we will gradually push the product to mobile phone screens, camera lenses, high-end ceramic targets and other production applications. "
