White corundum is made of bauxite and graphite electrode as main raw materials by using a new ultra-fine powder technology. In the production process, raw materials need to be added, stirred, molded and fired at high temperature. The use characteristics of white corundum: high fire resistance, stable high-temperature performance, no explosion and no pulverization. Corrosion resistance, high hardness and certain toughness. White corundum is suitable for all kinds of refractories made at high temperature. Widely used in chemical industry, glass, all kinds of metal abrasive surface polishing, can also be used for water filtration. High temperature characteristics of white corundum: no explosion, stable performance and no pulverization. The summary of these characteristics is based on years of experience and experiments, and this characteristic of white corundum is known. White corundum is not easy to scratch the surface of grinding tool when grinding, because white corundum particles are small and dense. It will not lead to the surface discoloration of different materials. After polished by white corundum, the surface of the abrasive tool is smooth and has no color difference. ?
