Brown Corundum, HS Code 28181010, CAS No. 1344-28-1, it is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature (approximately 2000 degrees Celsius). Its chemical composition consists mainly of Al2O3 (94,5-97%) and vestigial amounts of TiO2, SiO2, Fe2O3, CaO and MgO.
Brown Corundum is characterized by good toughness, high mechanical resistance and hardness (9 in Mohs scale). The micro hardness of the material reaches about 1900kG/mm2. Specific gravity (density) equals 3,90+/-0,05 g/cm3. Bulk density depending on size equals 1,68-1,95 g/cm3. It has relatively high thermal conductivity and low thermal expansion. As regards electricity it is an insulator.
