Note
Brown Fused Alumina is a kind of artificial corundum made by fusing bauxite and other elements in electric arc furnaces, and It is both hard and tough material. High strength fusing under very high temperatures makes the materials in the furnaces liquid, and the materials are then cooled down and become crystal forms with high hardness and density. Brown Fused Alumina is widely used in shaped refractory products, unshaped refractory materials, sandblasting media, grinding media, abrasives grains, etc.
