White corundum is an artificial ceramic material with high hardness, high density and high wear resistance. Its main component is aluminum (Al2O3), and usually contains a small amount of other additives such as yttrium oxide, silicon, titanium, etc. The hardness of white corundum ranks second in Mohs hardness, second only to diamond, so it is widely used in high wear resistance, high strength and high temperature rings in porcelain, abrasive and other fields. White corundum also has good corrosion resistance, thermal conductivity and insulation properties, and is also used in special occasions such as medical surgical knives and furnace components.
