Brown Fused Aluminum Oxide for Refractory
Brown Fused Alumina is an important synthetic corundum refractory mineral made from reduced fusion of quality
bauxite, iron and coal in electric arc furnace under 2500 degree. It's hard, tough, dense, fire-proof, sharp-edged,
wear resistant, and corrosion resistant material and widely used in production of grinding wheels, sand papers,
sand cloth, sanding belt, production of refractory bricks, steel making industry, ceramic, glass, cement industry etc.
Brown Fused Alumina Refractory Grades is a mineral with fine particle distribution for shaped and unshaped
refractory products in fire-proof, precision casting, foundry and coating industries.
