◆ Product description

Tabular Alumina appears white granular or powder, is produced by grinding alumina powder, then does molding and high temperature sintering.

Tabular Alumina has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum, with high purity, good volume stability and minimal reburning shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high temperature treatment.
