Spherical Aluminum Nitride Powder Description

Spherical Aluminum Nitride Powder is manufactured through a carbothermal reduction process utilizing a highly active aluminum source and a carbon source. AlN exhibits remarkable thermal conductivity, being ten times higher than that of Al₂O₃, ranging from 80 to 320W/m·k. In contrast to the anisotropic heat dissipation of BN, it does not share the same characteristics. This powder boasts a high rate of sphere formation, a small specific surface area, a narrow particle size distribution, and elevated purity.

As a result, Spherical Aluminum Nitride Powder holds significance as a crucial raw material for creating AlN ceramic substrates and manufacturing various high thermal conductivity products.
