Aluminum Nitride Powder, AlN, CAS 24304-00-25


New product

Aluminum Nitride (AlN) Powder is a grey-white powder with a hexagonal crystal structure. Moh's hardness is 9. At room temperature, aluminum nitride has high strength, and the strength decreases slowly with the increase in temperature. Good thermal conductivity and low coefficient of thermal expansion make it a good heat-resistant impact material. It has excellent thermal shock resistance.
