Brown Fused Alumina
White Fused Alumina
Ceramic Abrasive
Zirconia Fused Alumina
Silicon Carbide
It is produced by fusion of calcined bauxite in electric arc furnace. The impurities fully react and precipitate, and slowly cool and crystallize. The brownish colored product shows extreme toughness and strong crushing resistance.
