Product Description

Process of Production :

Tabular alumina is produced by using High grade industrial alumina as primary raw material, They are ground and fat sintered at super-High temperature (>1900degrees).
The product has a close packing structure of corundum grain size in the range from 1-2 µm to 100-200 µm with cross bonding and homogenized distribution, resulting in maximum packing density.

Character :

It is characterized by high refractoriness, high bulk density, High thermal shock resistance, High wear-resistance, high purity and High chemical resistance, complete crystal tabularization and low porosity.

Application :

It has been widely used as the material of choice in unshaped and shaped high performance refractories used in a variety of industries (Steel, Foundry, cement, glass, petrochemical, ceramic and waste incineration). Other common non-refractory applications include its use in kiln furniture and for metal filtration.

It is the preferred material to substitute for imported sintered alumina.
