Brown Fused Alumina(Brown Fused Aluminium Oxide) is a type of electrofused artificial corundum made by process fusing bauxite and other elements in electric arc furnaces. Fusion under very high temperature makes the materials in the furnaces liquid materials. The materials are then cooled down and become crystal forms with high hardness and density. So Brown Fused Alumina is also called Brown Corundum. Brown Fused Alumina widely used in refractory products, unshaped refractories, sandblasting media, grinding media, abrasives grains, etc.
