Process Of Production
A dense refractory material, our tabular alumina is a well-sintered, crystalline alpha alumina used as both a refractory aggregate and as fines addition to the matrix.
Tabular Alumina is a pure sintered α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1890°C
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
1 . high refractoriness,
2 . high bulk density,
3 . High thermal shock resistance,
4 . High wear-resistance ,
5 . high purity and High chemical resistance, complete crystal tabularization
6 . 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
