White corundum is made of high-quality aluminum oxide powder as raw material, which is crystallized by electromelting. High purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable thermal performance, its hardness is slightly higher than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, small calorific value, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability. It is used to make abrasives, suitable for grinding fine-grained abrasives such as high carbon steel, high speed steel and stainless steel, and can also be used for precision casting and advanced refractory materials.
