NR5028 Spherical Aluminum Nitride Powder

Spherical Aluminum Nitride Powder Description

Spherical Aluminum Nitride Powder is produced by a carbothermal reduction process using a highly active aluminum source and a carbon source. The thermal conductivity of AlN is ten times that of Al₂O₃, reaching 80~320W/m·k, not the same characteristic of anisotropy heat dissipation of BN. It features a high sphere formation rate, small specific surface area narrow particle size distribution, and high purity.

Therefore, Spherical Aluminum Nitride Powder is an important raw material for the preparation of AlN ceramic substrates and the production of various types of high thermal conductivity products.
