high purity brown alumina is bauxite, coke (anthracite) in raw materials, smelting in electric arc furnace at high temperature. The main chemical compositions are Al2O3,TiO2 and little SiO2,Fe2O3 and so on. Hardness HV1800-2200,higher toughness than Sic. The abrasive made from it is suitable for high tensile strength metal, such as a variety of common steel, malleable iron and hard bronze. It also can be used to the advanced refractory.
