Description

Refractory material, castable refractory, ceramic refractory, coating abrasive, coated abrasives, abrasive grinding, abrasive gritï&frac*4;Œcorundum, 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 gritï&frac*4;Œcorundum, 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 *****
