Tabular Alumina, sometimes called TWA, is a pure,sintered corundum that does not add any additives such as MgO, B2O3, and shrinks completely. It has coarse crystals and a well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. Crystal structure, with small pores and many closed pores, and the porosity is roughly equivalent to that of Fused Alumina. With high purity, good volume stability, and minimal re-fireshrinkage, Tabular Alumina performs good as the refractory materials or castables. Tabular Alumina has good thermal shock stability and bending strength after the production of high temperature treatment.
