Pink Corundum of our company is a kind of high-grade Pink Corundum, which is made from metallurgical chrome green and industrial grade Alumina by chemical reaction at high temperature above 2000 ° C. Its color is pink, its hardness is similar to that of WFA, and its toughness is higher than that of WFA. Pink Corundum has high viscosity and good permeability because of containing chromium oxide, which can prevent the erosion and penetration of molten slag to a great extent. It is also widely used in the high temperature field of bad environment, including non-ferrous metallurgical furnace, Glass Furnace, carbon black reactor, garbage incinerator, refractory cast able, etc.
