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