More info

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 Storage and Packing

Aluminum Nitride (AlN) Powder should be stored in a cool, dry environment and avoid heavy pressure. The powder without surface treatment should not be exposed to air during use to prevent moisture absorption and aggregation, which will affect the dispersion performance and use effect. HM offers vacuum-sealed packaging including 100g/bag, 500g/bag, 1kg/bag, and 25kg/drum, or customized packaging as per specific requirements.
