Product Description

Tabular alumina is made by adopting the imported industrial alumina as starting material, withinout any additives,fast sintered at super-high temperature(>1900du ). The product has a close packing structure of corundum grain size in the range from 1-2um to 100-200um 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.
