Brown fused alumina

Brown Fused Alumina for Refractory
Brown Fused Alumina is an important synthetic corundum refractory mineral made from redused 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. Our Brown Fused Alumina Refractory Grades is a high grade refractory material with high purity, high cleaness, coarse grain, low magnetic contents, high density, high bulk density, chemical stability, low prosity rate, nice crystal struction, corrosion and acid resistant. No cracks, corrosion or spot during production of refractory products.
