Description:
99.5% white fused aluminum oxide refractory, 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 good volume stability and thermal shock resistance. As a most common used corundum in the abrasive industry,white fused aluminum has a long history in applications because of it’s high hardness,good self-sharpening advantages. By adopting high quality grade materials,strict quality control system,developed production technology, HAIXU’s white fused alumina get a high purity,stable quality and good distribution.
Characteristic:
With smelting point up to 2250?, whit aluminum oxide is a high level refractory material. It has advantages including high purity,good acid-alkali resistance, temperature resistance, high thermal stability.
Applications:
Refractory, casting,foundry.
Bonded abrasives and Coated abrasives.
Ceramic Tiles special ceramics.
Fluidized Bed Furnaces and Skin/Dental Care.
