Brown Fused Aluminum Oxide HS Code 28181010, CAS No. 1344-28-1, (called as corundum sand in China) is made by chemical grade calcined alumina with electron fusing in temperature over 2000ºC. Characterized with phase, thermal and chemical stability, it is idea raw material for products like ceramic roller, kiln furniture and refractory products for metallurgy. Brown Fused Aluminum Oxide 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.
