Product Description
Tabular alumina is produced by sintering ball-formed, intermediately burned calcined alumina at a temperature just under the 2040º C melting point of aluminum oxide.
These tabular alumina balls are then crushed, graded or screened, ground and blended to a wide range of granular or powdered particle size distributions.
APPLICATION
It has been widely used as the material of choice in unshaped and shaped high performance refractoriesused 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.
