Longer Melting 99.5% Fixed Furnace Barmac Crushed White Corundum for Mobile Phone and Electronic Industries

1. White Fused Alumina Descriptions

White corundum 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.
