Refractory materials, castable refractory, ceramic refractory, coating abrasive, coated abrasives, abrasive grinding, abrasive grit. Sub-white features hardness of white corundum, the toughness of brown corundum, mainly used in the manufacture of abrasives, abrasive and high-quality refractory instead of white corundum and dense corundum

Refractory materials, castable refractory, ceramic refractory, coating abrasive, coated abrasives, abrasive grinding, abrasive grit. 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. Brown Fused Aluminum Oxide has brown color, high hardness and great toughness. The abrasives tools made of brown aluminaum oxide are suitable for grinding carbon steel, malleable cast iron and hard bronze. It used for refractiry aluminum oxide lining mixyure, pouring materials castables, etc.
