Introduction of white corundum

White corundum is a kind of white artificial corundum. Like natural corundum gems, it has the characteristics of high hardness, high temperature resistance, stable chemical properties and purity. The Mohs hardness of white corundum is 9, second only to diamond, the highest use temperature is close to 2000 °C, and the Al2O3 content is more than 99 %. These excellent material properties make white corundum more and more widely used in today 's industrial production.
