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.

 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. Physical Data: Color: White Shape: Blocky with sharp edges Mohs Hardness：

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

White fused corundum abrasives is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great

White corundum abrasive micropowder are produced with acid wash and water pickled process, so it will get a more purity powder. Comparing with the ones with milling production, Acid pickled WFA powder has better size distribution which is suitable for making ceramic membrane tubes, honing stone, even for skin cleaning. PRODUCT FEATURES: High hardness and
