White corundum 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. 1. Performance: White, with more than 99% α-type crystals, high purity, high hardness and high toughness. Strong cutting force, good chemical stability, good insulation. 2. Scope of application: Grinding and polishing of metals, crystals, semiconductors, manufacturing of oil stones, grinding wheels, sandpaper, emery cloth abrasive belts, wet or dry sandblasting on the surface of workpieces, suitable for processing hardened steel, high-speed steel, high-carbon steel, etc. , a material with high tensile strength, can also be used as a high-grade filler for catalysts, insulators, precision casting sand, paint coatings, and epoxy resin insulators.
