Ladles Nozzles Sintered Alumina Castables High Refractoriness Bulk Density
Tabular Alumina
ROCESS OF PRODUCTION
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:
It is characterized by high refractoriness, high bulk density, High thermal shock resistance, High wear-resistance ,high purity and High chemical resistance, complete crystal tabularization and 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
