Product Description
Fire Brick Tabular Alumina Ball With Alpha Alumina In Corundum form
Tabular Alumina Ball is a pure sintered alpha-alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperatures in excess of 1800°C.
Tabular Alumina Ball has characteristic large, well developed hexagonal tablet shaped alpha-alumina crystals of up to 200 µm length. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores,which are entrapped upon re-crystallization during rapid sintering.
We offer tabular alumina size as below:
Lumps size:,0-0.5mm,0.5-1mm,1—3mm,3-5mm 5—8mm
Fine powder:180mesh 200mesh 325mesh
Customized size is available

Applications
Tabular Alumina is the aggregate of choice in unshaped and shaped high performance refractories.
It is used in a variety of industries such as steel, foundry, cement, petrochemical, ceramic and waste incineration.
Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support.
Ground Tabular is an excellent product to be used as a filler in epoxy or resin systems
where high dielectric strength, thermal conductivity or abrasion resistance is desired.
