What is White Fused Alumina?
White fused alumina is obtained by high-purity low-sodium alumina powder after high-temperature melting, cooling, crystallization, and crushing. It is a particle with tightly controlled particle size distribution and consistent appearance.
Performance: White, with more than 99% a-type crystals, high purity, high hardness, high toughness, strong cutting force, good chemical stability and good insulation.
