Tabular Alumina

Tabular Alumina is the pure sintered alpha alumina material that has been fully densified by rapid-sintering without the use of sintering aids at tempertatures in excess of 1800 Degrees Celsius.When the internal crystalline structure of tabular alumina is examined, large plate-like or table-like crystals are apparent. The shape of these crystals gives "tabular" alumina its name.The excellent 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.

The application scope of Tabular Alumina:
1. unshaped and shaped high performance refractories.
2. replace fused alumina and white fused alumina in some application position, and improve the performance of refractory material.
3. a variety of industries such as a steel, foundry, cement, petrochemical, ceramic and waste incineration.
4. electrical insulators, kiln furniture and as a catalyst support.
5. used as a filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.
