Process Of Production

 

 

Tabular Alumina is a pure material sintered at super - high temperatures without MgO and B2O3 additives,Its microstructure is a two - dimensional polycrystalline structure with well - grown large tabular α - Al2O3 crystals .

 

Tabular Alumina has a lot of small closed pores in individval crystal , Al2O3 content is more than 99 % .Therefore it has good volume stability and thermal shock resistance , high purity and refractoriness , excellent mechanical strength , abrasion resistance against slag and other substances.

 

 

Product Performance

 

Tabular alumina balls are sintered alpha alumina with very high-purity, high-density, fully shrunk, coarse crystalline alpha aluminas. When the internal crystalline structure of tabular alumina is examined, large plate-like or tablet-like crystals are apparent. The shape of these crystals gives "tabular" alumina its name.

Tabular alumina is produced by sintering ball-formed calcined alumina at a very high temperatures around 2040°C (3704°F), which is the fusion point of aluminium oxide. The alumina is formed from pure aluminum oxide. Practically all porosity and shrinkage is removed under such high temperature. Essentially tabular alumina is 100 percent alpha alumina (corundum).

These tabular alumina balls are then crushed, graded or screened, and ground to a wide range of granular or powdered particle-size distributions. Tabular Alumina can appear as white crystalline granules or powder. Depending on requirements, ball sizes are produced from 1/8 to 1 inch (tolerance ± 1 mm).

 

 

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.
