These are alumina particles with a high aspect ratio and a purity of 99.0% or higher. They are also suitable as fillers for electrical insulation and wear resistance!
PWA is a high-quality alumina powder composed of plate-like crystals with an Al2O3 purity of 99.0% or higher. Alumina is excellent in heat resistance and electrical insulation, and it is chemically inert, unaffected by acids or alkalis. It also has a hardness second only to silicon carbide. For this reason, it is expected to be used as a filler material (filling material, heat dissipation (thermal conductivity)) aimed at providing insulation and wear resistance. Our plate-like alumina has the following features: 1) Unique shape: high aspect ratio plate-like 2) Lineup: average particle size ranging from 3µm to 30µm 3) Sharp particle size distribution: our proprietary classification technology [Expected Applications] - Filler material: providing insulation and wear resistance - Providing low aggressiveness to the counterpart - Providing optical properties (such as light diffusion)
