Specification of Aluminum Nitride Powder

Description Aluminum nitride (AIN) is a binary covalent compound. The crystal structure is a hexagonal fibrous zinc ore crystal structure. It is white and gray, and the heating coefficient is high. The materials at high temperature are stable. It can match the thermal expansion coefficient of the silicon material and it is the ideal electronic packaging heat dissipation material. Because of its advantages such as high strength and corrosion resistance, it is widely used in ceramic substrates, heat-conducting fillers, piles, evaporation boats, and ceramic structure devices.
