Tabular Alumina Tabular alumina as catalyst support Excellent thermal volume stability High refractory,good chemical purity

Tabular Alumina

Tabular Alumina is a pure sintered α-alumina materials that has been fully densified by rapid-sintering without  the use of sintering aids at temperature in excess 1900°c.

Tabular alumina has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm length.

Features

1. low open porosity and large crystals with closed spherical pores

2. high refractoriness, high mechanical strength and abrasion resistance

3. good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion.

Application

It is used in a variety of industries such as steel, foundry, petrochemical, ceramic and incineration.

Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support.
