Aluminum Nitride Powder, AlN, CAS 24304-00-25
HMNP-1679
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.

Aluminum Nitride Powder Applications
Aluminum Nitride (AlN) powder is always used in manufacturing high-performance ceramic parts, and preparation of metal-based and polymer-based composites and other areas.
Aluminum Nitride Powder Storage and Packing
Aluminum Nitride (AlN) Powder should be stored in a cool, dry room and avoid heavy pressure. The powder without surface treatment should not be exposed to air during use to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect.
