Tabular Alumina is a pure, do not add any additives and to firing shrinkage thorough sintered corundum, coarse crystalline, well-developed crystal structure. Plate-like crystal structure, porosity and closed stomata more the Porosity and fused corundum roughly, high purity, good volume stability, minimal dead burned contraction, for the production of refractory or high temperature castable has good thermal shock resistance and bending strength, but the price is high compared to the other alumina.
