Product Description

Refractory Material White Fused Alumina (WFA) Powder 99.2% min 200 mesh

Product Description

Feature
White Fused Alumina has high purity, high whiteness, high hardness, acid corrosion resistance, good thermal stability.
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 2000 °C.
9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.
Details information
White Fused Alumina is a high purity, synthetic mineral, manufacturered by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000ºC.
Application: Wear-resistant and refractory products, reusable abrasive, grinding and polishing Media, Ceramic grinding wheels, Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces and Skin/Dental Care.
