Tabular Alumina

Tabular alumina is a kind of pure sintered alumina,which is sintered and completely shrink without adding any additive ,with coarse crystals and well-developed α- Al2O3 crystal structure. The tabular crystal structure is characterized by narrow pores,with more closed porosity, almost the same apparent porosity compare with fused corundum ,high purity, good stability volume density , tiny refiring shrink.
