High Purity Aluminum Nitride

Aluminum nitride is a kind of advanced thermal conductivity material. It not only has the characteristics of ceramic insulation and low thermal expansion, but also has the thermal conductivity same as metallic copper and aluminium. Its thermal conductivity is 7 to 10 times that of alumina while its mechanical property are similar to alumina ceramics. The coefficient of thermal expansion is similar to silicon. It is mainly used to make the support and heat dissipation substrate of high power semiconductor integrated circuits. At the same time, it is wildly used  in 5G communications, transportation, power, consumer electronics and defense industry and other fields. Carbothermal reduction nitriding technology is used in the production of high purity aluminum nitride powder. With such technology, the produced high purity aluminum nitride powder can apply to generate high thermal conductivity aluminum nitride ceramic substrate and thermal conductive filler.
