4.Application of Tabular Corundum Powder
As the high temperature sintered tabular corundum products have superior characteristics in various aspects, it is widely used in the production of refractory products, such as the addition of high aluminum amorphous refractory, the addition of aluminum carbon refractory brick, spinel brick, magnesium aluminum carbon brick, in order to improve the good thermal shock resistance and bending strength of the products at high temperature. The products are widely used in steel, casting, ceramics and other industries.
