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.
