1.Description of Tabular Corundum Powder: tabular corundum is a kind of pure sintered corundum without additives. The calcination temperature is as high as 1900-2200℃, and the product is a well-developed α- Al2O3 crystal structure.Plate like crystal under microscope,there are a lot of round closed pores in the crystal,the pore size is small, and the porosity is equivalent to that of fused corundum.

3) high purity, superior creep resistance and peeling resistance
4) high mechanical strength and good wear resistance
5) superior acid and alkali resistance
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.
