Sintered Tabular Alumina - China

1 - Description Sintered tabular alumina is a kind of pure sintered

corundum, which is sintered and completely shrink without adding any

additive, such as MgO or B2O3, with coarse crystals and well-developed

alpha Al2O3 crystal structure.

The tabular crystal structure is

characterized by narrow pores, with more closed porosity, almost the

same apparent porosity compare with fused corundum , high purity, good

stability volume density , tiny refiring shrink.

After high

temperature treatment, tabular alumina is used for refractory and

castable characterized by good thermal shock stability and flexural

strength.

but the price is higher than the other alumina.

2 - Performance

Tabular alumina is characterized by good heating volume temperature performance and good thermal shock resistance.

3 - Usage

Tabular alumina is the perfect refractory raw material, which is widely used as the aggregate for producing various alumina refractory, it also can be used in other monolithic refractory.

It can replace fused alumina and white fused alumina in some application position, and improve the performance of refractory material.
