[0002] White corundum is an industrial ceramic material with high hardness, high toughness and high wear resistance, also known as high-performance ceramics. It is made of high-purity alumina and silicon dioxide and other materials sintered at high temperature. It has high density and uniform fine grain structure. White corundum has high hardness, second only to superhard materials such as diamond and silicon carbide, and can maintain stability under high temperature and high pressure environment; its high toughness can ensure that it will not break when impacted, and it also has anti-corrosion, wear resistance, insulation and other characteristics. When white corundum is produced, the raw materials will be crushed by a crushing mechanism.
