Description:
White fused alumina / white corundum is one of the most popular alumina abrasives , which made from the high quality
alumina by melting above 2000 in the electric arc furnace and cooling. As a kind of alumina grinding media, it is widely used in polishing, lapping and blasting.
Applications:
1. Abrasive tools
2. Refractory material
3. Lapping, polishing, non-skid tile, and pressure blasting media
Competitive Advantage:
white corundum abrasive is white with the main crystal phase alpha-Al2O3.
The white corundum abrasive 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.
