refractory ,abrasive, coated abrasive,castable refractory,abrasive grinding . high alumina corundum "Shaolin" brand sub-white corundum is one of our main products, and manufactured in electric arc furnace using high-quality bauxite as major starting material 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
brown fused alumina is manufactured in electric arc furnace using bauxite as raw material, shows brown color。with high hardness and high toughness, it is an important raw material of abrasive and refractory industries.
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
