white fused alumina corundum,a kind of high-grade refractories, 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.



Feature

High purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable thermal performance.

Its hardness is slightly higher than brown corundum, toughness is slightly lower, grinding ability is strong, calorific value is small, and efficiency is high.

Abrasive tools made from it are suitable for grinding fine-grained abrasives such as high carbon steel, high-speed steel and stainless steel. They can also be used for precision casting and advanced refractory materials.

The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness.


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.
