Tabular Alumina is also known as white sintered alumina, is a pure sintered α-alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900℃.

Typical Physical Properties of Tabular Alumina
It has characteristic of 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.
It 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.
Aggregate of Choice
It is the aggregate of choice in unshaped and shaped high performance refractory.
