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. TA has extremely high refractoriness, high mechanical strength and abrasion resistance, very good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion. TA is the aggregate of choice in unshaped and shaped high performance refractory. It is used in a variety of industries such as steel, foundry, petrochemical, kiln furniture and as a catalyst support. Ground TA is an excellent product to use as filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.

5. Tabular Alumina Applications
Tabular Alumina is used in the refractory industry. Application is shaped and unshaped products, like bricks or specially shaped products e.g. sliding gates, porous plugs for steel ladles and shaped products for the glass industry. Furthermore kiln furniture like ceramic wheels are produced for the application in ceramic kilns. Another application of the Tabular balls is the filtering in Aluminium metal production.
