Product Description







White aluminum oxide all call white corundum, white electro corundum, it is smelted basis of alpha alumina, which is electrically fused in high temperature 2000℃. It is pure white and high hardness, but toughness lower than that of brown fused alumina. It is available for difference application and size, attractive price and fast delivery.



White aluminum oxide (also known as White Corundum) is made of industrial alumina powder as the main raw material, which is smelted in an electric arc furnace at a high temperature of more than 2000 degrees and then cooled. It is a high-purity synthetic mineral. After crushing and shaping, magnetic separation to remove iron, and sieving into various particle sizes. It has a dense texture, high hardness, sharp horn-shaped grains, high refractoriness, and is very hard and corrosion-resistant.





The hardness of White Aluminum Oxide is slightly higher than that of brown aluminium oxide, the toughness is slightly lower, the purity is high, the self-sharpening is good, the grinding ability is strong, the calorific value is small, the efficiency is high, the acid and alkali corrosion resistance, and the high temperature thermal stability is good. Made of white aluminum oxide sand,
it is suitable for grinding fine-grained abrasives such as high carbon steel, high speed steel and stainless steel. White aluminum oxide segment sand can also be used for precision casting and advanced refractories.






1.As a base material for abrasive blasting.
2.As raw material for grinding tools such as grinding wheels, sandpaper, and abrasive belts.
3.As raw material for refractory materials.
