Product Description

Refractory material, castable refractory, ceramic refractory, coating abrasive, coated abrasives, abrasive grinding, abrasive grit，corundum, ceramic material White corundum is prepared with alumina as starting material, in the high-temperature smelting electric arc furnace, Its color is white and main phase isα-Al2O3, the hardness is slightly higher than corundum, it features properties of acid and alkali resistant, good abrasion resistance, anti-erosion and volume stability at high temperature, It is a kind of important raw materials used to manufacture abrasives and advanced refractory. Refractory material, castable refractory, ceramic refractory, coating abrasive, coated abrasives, abrasive grinding, abrasive grit，corundum, ceramic material After calcinations and acid treatment to sub-white corundum, its residual carbon content and impurity are reduced, so that products do not chalk and burst in application ZHENGZHOU WHALE REFRACTORY CO.LTD contact name: JOHN DUAN *****
