Difference Between Brown Fused Alumina And White Fused Alumina

White corundum is to quality aluminum oxidation powder for raw materials, white corundum by electric melt refined crystal and into, purity high, and since sharp sex good, and acid alkali corrosion, and resistance high temperature, and hot state performance stable, white corundum hardness is slightly higher than Brown corundum, toughness slightly low, purity high, and since sharp sex good, and grinding capacity strong, and heat small, and efficiency high, and acid alkali corrosion, and resistance high temperature hot stability good, with white corundum grain degrees sand made abrasives, applies Yu grinding high carbon steel, and high-speed steel and the stainless steel, fine grain degrees abrasive, white corundum also can for precision casting and senior refractory.
Corundum is bauxite, coal, scrap iron as raw materials, in an electric arc furnace and is formed by high temperature smelting, is Brown, toughness, hardness 1800-2200Kg/mm2, bulk density ≥ 3.85g/cm3, high temperature resistance, fire resistance of up to 1850, refractory materials, can also be used as abrasives.
