Tabular Alumina
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
• Good resistance to thermal and mechanical shock
• high purity and refractoriness
• Excellent abrasion resistance
• High thermal conductivity
• low porosity
• good volume stability
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
