White corundum and white corundum micro-powder is made of high-quality aluminum oxide powder as raw materials, and is crystallized by electromelting. It has high purity, good self-sharpness, acid and alkali corrosion resistance, high temperature resistance and stable hot state performance. It has slightly higher hardness than brown corundum, slightly lower toughness, high purity, good self-sharpness, strong grinding ability, low heat output, high efficiency, acid and alkali corrosion resistance and high temperature thermal stability. It is used to make abrasive tools, suitable for grinding high carbon copper, high speed steel and so on. White corundum powder is widely used, such as polly or acrylic art atomized aesthetic processing, sandblasting in the process of TV screen, high-grade refractory materials and other ceramic additives.
