Application of AlN powder:

The aluminum nitride powder has high purity, small particle size, uniform distribution, high surface activity, low bulk density, and good injection molding performance. It can be used in composite materials, has good matching with semiconductor silicon, and has good interface compatibility, which can improve the mechanical properties and thermal conductivity of composite materials.

SEM & XRD of AlN powder:

Storage conditions:
AlN powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
