1. Tabular Alumina Introduction
Tabular Alumina(TA) is a pure sintered a α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900℃. TA has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm 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.
