Tabular Alumina
Tabular Alumina is the pure sintered alpha alumina material that has been fully densified by rapid-sintering at temperatures in excess of 1800ºC. Tabular Alumina has characteristic large, well developed hexagonal tablet shaped alpha alumina crystals of up to 200 um 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.
Tabular Alumina has extremely high refractoriness, high mechanical strength and abrasion resistance, high chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion.
Tabular Alumina is used in a variety of industries such as steel, foundry, cement, petrochemial, ceramic and waste incineration. Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support.
