China High Quality White Corundum 1-2mm Refractory
Thermal resist Al2O3 Electrocorundum, 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.
With smelting point up to 2250℃, white aluminum oxide is a high-level refractory material. It has advantages including:
High purity up to 99% Al2O3
Good acid-alkali resistance
Temperature resistance
High thermal stability
High hardness up to Mohs 9.0
