Description

White Tabular Alumina Almatis

Product Description

Tabular alumina, also known as alpha alumina, is a pure sintered corundum that is completely sintered and shrunk without any additives such as MgO and B2O3. Plate-like crystal structure, small pores and more closed pores, and the porosity is roughly equivalent to that of fused corundum, with high purity, good volume stability, and minimal refiring shrinkage. It has good thermal shock stability and flexural strength, but the price is higher than other aluminas.

Application

Tabular alumina is the aggregate of choice for unshaped and shaped high performance refractories.

Used in steel, foundry, cement, petrochemical, ceramics, waste incineration and other industries.

Other common applications include use in electrical insulators, kiln furniture and catalyst supports.

Advantages

Tabular alumina is a dense, shrunk, sintered α-Al2O3 aggregate structure composed of 50-400 μm grains. Tabular corundum gets its name from the shape of its grains like slabs. Tabular alumina was prepared by rapidly calcining ultrafine α-Al2O3 pellets at a temperature slightly lower than the melting temperature. After heat treatment, crush or grind 18-20mm pellets to obtain tabular corundum of various sizes.
