Application 1. Aluminum nitride powder with high purity, small size, high activity, is the main raw material for the manufacture of high thermal conductivity aluminum nitride ceramic substrate.  2. AlN ceramic substrate, high thermal conductivity, low expansion coefficient, high strength, high-temperature resistance, chemical corrosion resistance, high resistivity, dielectric loss is small, think of the large scale integrated circuit substrate and packaging materials.  3. More than the traditional aluminum nitride alumina, high hardness, abrasion-resistant ceramic materials is new, but because of its high cost, only for the serious wear of the parts.  4. High melt erosion and thermal shock resistance of AIN ceramics by heat, can be made of GaAs crystal crucible, Al evaporation dish, magnetic fluid generating device and the high-temperature corrosion of turbine components, using the optical properties for the infrared window. Aluminum nitride thin film can be made of the high-frequency piezoelectric element, ultra large scale integrated circuit substrate.  5.Aluminum nitride, heat resistance, erosion resistance of the molten metal, but the acid stability in alkaline solution Easy to be eroded.AIN new surface is exposed to moist air will react very thin oxide film. Using this characteristic can be used like aluminum, copper, silver, lead and other chemical properties of metal crucible for metal melting and casting mould of.AIN ceramics is better, can replace toxic beryllium oxide ceramics are widely used in the electric industry.
