Introduction:
Aluminum nitride AlN is the only stable compound of Al and N, and is the semiconductor with the largest energy gap in the III-V group. Aluminum nitride atoms are combined by covalent bonds, which have good chemical stability and high melting point. At the same time, it has high mechanical strength and good electrical insulation properties. It is a piezoelectric material. It has good injection molding properties, can be used in composite materials, has good matching with semiconductor silicon, good interface compatibility, and can improve the mechanical properties and thermal conductivity and dielectric properties of composite materials.
Product advantages:
The particle size distribution is concentrated,
Good dispersion,
Low metal impurity content,
Low oxygen content,
Low coefficient of thermal expansion,
Strong hydrolysis resistance.
The particle size is complete (nano-level aluminum nitride 100-200nm, 300-500nm, 1-2um, 3-5um, 10um, etc.), and surface treatment can be done according to customer requirements.

Aluminum nitride 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, which will affect the dispersion performance and use effect. Surface treatment can be done according to user requirements.
