White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency. White fused aluminum oxide becomes the first choice for

White aluminum oxide is white with the main crystal phase alpha-Al2O3,it is made from the high quality alumina by melting above 2200℃ in the electric arc furnace and cooling.   White aluminum oxide produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can

AL2O3 alumina polishing powder 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

Applications Mainly used in abrasive industry, such as bonded abrasives, coated abrasives. Bonded abrasives Coated abrasives Gunning material Refractory raw materials Packaging 25 kg bags on pallet up to 1 ton 1 ton loose in big bag As requirements Technical Composition: FEPA Average grain size(µm) FEPA Average grain size(µm) FEPA Average grain size(µm) FEPA Average

 White Aluminum Oxide is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size. It is used in many applications including grinding and cut off wheels, coated abrasives, laminates, coatings, blasting, lapping and polishing.
