Corundum is divided into natural corundum and artificial corundum. Natural corundum is a pure alumina (Al2O3). The main mineral component of artificial corundum is physical corundum. Artificial corundum is divided into brown corundum (A), white corundum (WA), chrome corundum (PA), zirconium corundum (ZA), black corundum (BA), single crystal corundum (SA), microcrystalline corundum (MA) and the like. The brown corundum is mainly made by using aluminum bauxite, iron filings and anthracite in the electric arc furnace by melting and reducing impurities; white corundum is obtained by melt crystallization of aluminum oxide powder in an electric arc furnace; other corundum is different in alumina content. A certain amount of other oxide-derived substances having different properties are added during the melting process. A large number of corundum applications are brown corundum and white corundum.
