Product Description

What is the white corundum micro powder used for
White corundum is made of high quality alumina powder as raw material, which is made by melting and cooling in the high temperature arc above 2000ºC. It has high hardness, slightly low toughness, high purity, good self-sharpness and strong grinding ability, and is also used as advanced refractory data. So what is the white corundum micro powder used for?
White corundum powder is made of electrofused white corundum. It has the characteristics of high purity, good self-sharpness, high hardness, slightly low toughness, strong grinding ability, while the white corundum powder is mostly white, small heat value, high efficiency, high temperature resistance, good thermal stability, acid and alkali corrosion resistance and other characteristics.
White corundum micro powder is not only advanced abrasive materials, but also advanced grinding and polishing materials, advanced refractory materials, or a very good insulator, with strong cutting ability, mainly suitable for grinding and polishing fine objects, or do advanced refractory materials.
Due to the special nature of white corundum powder itself, it has become the first abrasive of more and more high-end industries. The grinding tools processed with it are suitable for grinding high carbon steel, high speed steel and all kinds of stainless steel. It is also widely used in fine casting, iron and steel refractory materials, chemical refractory materials, electric porcelain, decoration porcelain and other daily special ceramics.
