High Temperature Sintered White Tabular Alumina TA 99.3% for Top Grade Refractories

1. Tabular Alumina Introduction

Tabular alumina is a kind of pure sintered corundum,which is sintered and completely shrink without adding any additive,such as MgO or B2O3,with coarse crystals and well-developed Al2O3 crystal structure. Tabular Alumina has characteristic large, well developed hexagonal tablet shaped alpha-alumina crystals of up to 200 µm length. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores,which are entrapped upon re-crystallization during rapid sintering.
