White alumina

Alumina is a white aluminum oxide powder as raw material in electric arc furnace at high temperature smelting together, the main chemical ingredient of Al2O3 content is generally higher than 98%, higher brown fused aluminum oxide than corundum hardness, toughness lower than corundum, better cutting performance. It is made ​​by grinding, suitable for grinding hardened alloy steel, high speed steel, high carbon steel. Fine-grained powder suitable for high-precision optics polishing and polishing. Others include precision grinding wheels, precision glass, crystal polishing, and fine ceramics can be used
