White fused alumina (WFA/WA/A) is also called white corundum or white aluminum oxide. It widely used in refractory industry, also can be used in ceramics shapes grinding wheels, sandpaper, blasting media, metal preparation, laminates coatings, lapping, polishing, grinding and hundreds of other applications.

white fused alumina 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

The Aluminum oxide powder for laminate flooring needs to meet the following indicators to be suitable for adding to the wear-resistant coating: Whiteness: The whiteness of aluminum oxide should be above 80. So the Al2O3 powder will not affect the color of the wear-resistant glue. Fluidity: Since alumina powder needs to be added to the

White fused aluminum oxide is a kind of WA abrasive grain, it is made by 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. White fused aluminum oxide is also characterized by its high purity, ability of self-sharpening,
