Corundum is mainly used for two types of wear-resistant materials and refractory materials in industry because of its two characteristics of "hardness" and "high temperature resistance". Grinding materials: can be made into grinding balls, grinding wheels, grinding discs, grinding paper and grinding powder (paste), etc. The abrasives manufactured with it are suitable for grinding various metals with higher hardness and higher tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc., and can also be used as super-precision grinding and polishing materials. Refractories: Corundum refractory products are resistant to high temperature and corrosion, and are widely used in the lining of various high-temperature electric furnaces and kilns and the production of corundum furnace tubes, furnace cores and high-temperature electric furnace accessories. In the chemical system, it is used as the special furnace lining of the reaction furnace and gasification furnace and as various reaction vessels and pipes.
We have White corundum(white alumina), brown corundum(brown alumina), black corundum(black alumina),green corundum(green alumina),welcome to inquiry.
