A detailed introduction to aluminum nitride

Aluminum nitride is a ceramic insulator, which gives aluminum nitride a high heat transfer capacity, so that aluminum nitride is widely used in microelectronics. Unlike beryllium oxide, aluminum nitride is non-toxic. Aluminum nitride is a metal treatment that can replace bauxite and beryllium oxide in a wide range of electronic instruments. Aluminum nitride can be prepared by the reduction of alumina and carbon or directly by aluminum metal nitride. In the air, when the temperature is higher than 700 ° C, oxidation will occur on the surface of the material.

Characteristics and application of aluminum nitride powder

Aluminum nitride (AlN) is a kind of diamond nitride inorganic non-metallic material, good thermal conductivity, low thermal expansion coefficient, is a good heat resistant impact material. Strong resistance to molten metal erosion, it is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator, with good dielectric properties, and has a good application prospect in the field of electrical component manufacturing. Ultrafine aluminum nitride powder is widely used in large-scale integrated circuit production.

High purity electronic grade polysilicon production line has been built in China

According to reports, after years of efforts, the national power investment Group Yellow River Hydropower Company has developed into a domestic integrated circuit application of high-purity electronic grade polysilicon production enterprises, by the third-party authoritative testing institutions testing, the quality of its products and Germany, Japan's well-known polysilicon quality. The industry believes that polysilicon is the "cornerstone" of the microelectronics industry and the photovoltaic industry, with the EU ending the implementation of the "double reverse" sanctions on China's photovoltaic, as the upstream electronic grade polysilicon industry is bound to usher in a new round of development opportunities.
