White corundum powder
White corundum powder is a kind of fine white corundum particles. Corundum is a mineral composed of alumina (Al2O3) with very high hardness. White corundum powder is a kind of fine particles obtained by grinding and screening of corundum ore. It usually has high hardness, high density and good chemical stability, and is suitable for various cutting, grinding and polishing processes, as well as the preparation of refractory materials, ceramic materials and so on. White corundum powder is widely used in industrial production and material processing.
