Brown corundum is made of high quality bauxite, iron scrap and anthracite by high temperature smelting in electric arc. After grinding and shaping by self-mill, magnetic separation of iron is carried out and sifted into a variety of particle sizes. The main chemical composition is AL2O3, and its content is 94.5%--97%.Its texture is dense, high hardness, brown, toughness, particle form ball, suitable for the manufacture of ceramic, resin high consolidation grinding tools and grinding, polishing, sandblasting, precision casting, refractory materials.In addition, brown corundum has the characteristics of high purity, dense texture, large bulk density, strong self-sharpening, good toughness, and extremely low magnetic content.The sintered abrasive tools are of deep blue color, free from reticular cracks and rust spots after firing, and are suitable for manufacturing ceramic, resin and high consolidation abrasive tools as well as for grinding and polishing.
