White aluminium oxide corundum grit was made from the high quality alumina by melting above 2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alpha Al2O3.
The white aluminium oxide corundum 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.
