White fused alumina sand was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-al2o3.The white alumina 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 be improved.

White Fused Alumina (WFA) is kind of electro-corundum, which produced by controlled melting of alumina in an electric arc furnace. Its iron-free, ultra purity and extremely hardness make it as excellent materials in sandblasting, precision casting, abrasive and refractory.
White Fused Alumina (WFA or WA) is an important raw material for advanced refractories and abrasives, a widely used raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and hundreds of other applications. As it is a very pure, low iron alumina, specific refractory applications include high tech refractory castables, isostatic pressed refractories, and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are high alumina content, low impurities, and stability at high temperatures.

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 the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and workpiece cleaning, and polishing.

Product Feature
1. The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency.
2. High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.
3. The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter.
4. Low oil absorption especially for water-based paint.
5. Neutral property with PH value around 7-8.
6. High whiteness. It doesn't affect the color of paints or coatings adding Al2O3 powder.
7. Resistant to most corrosive alkali and acid. It doesn't dissolve in water.
8. Resistant to high temperature up to 1900 C. 9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.
