Tabular Alumina

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.
