■ Specifications

 Aluminum nitride has a high strength at room temperature and its strength decreases slowly with increasing temperature. Thermal conductivity, thermal expansion coefficient is small, is a good heat shock materials. Anti-molten metal erosion ability, is cast iron, aluminum or aluminum alloy ideal crucible material. AlN or electrical insulator, good dielectric properties. Aluminum nitride powder is a high thermal conductivity, excellent electrical insulation properties of ceramic materials.

Our Company's production of aluminum nitride powder purity is high, the particle size is small, is bigger than the surface area, the surface activity is high, through the superficial cloth wrapper processing powder body, the oxygen content is extremely low (<0.1%), the insulation heat conduction performance effect is obvious. Should accept the rice noodle body to be possible to apply in the engineering plastics, enhances the betterment work plastic the performance and the mechanical strength and so on, good injection molding performance. Uses in the compound materials, is good with the semiconductor silicon match, the contact surface compatibility is good, may enhance the compound materials the mechanical property and the heat conduction insulating ability, widely applies the heat conduction silica gel and the heat conduction plastic, the resin, the LED electron seal material.

The aluminum nitride compound by our company based on new techniques is featured with high purity, even size distribution, large specific area, high surface activity and low apparent density, etc.
