Aluminum Nitride (AlN) Powder is a non-oxide semiconductor material with a wide direct bandgap of 6.12 eV. At room temperature, aluminum nitride exhibits high strength, and this strength diminishes gradually with increasing temperature. Its favorable combination of good thermal conductivity and a low coefficient of thermal expansion renders it an excellent material for heat-resistant applications. The outstanding thermal shock resistance of aluminum nitride makes it suitable for the manufacturing of high-performance ceramic components.

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.
