0-1mm 1-3mm 3-5mm white fused alumina white corundum

White fused alumina / White Corundum is a high-grade refractory material, which made from high-quality alumina powder by melting above 2000 ℃ in the electric arc furnace and cooling, classified into different grain sizes. The white fused alumina is the main raw material for the production of unshaped and shaped refractory materials.

Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.

White Fused Alumina in Abrasives/ Refractory

White fused alumina is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness and sharp in shape.
