Tabular Alumina 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 1900°C.
Tabular Alumina has characteristic large, well developed hexagonal tablet shaped alpha-alumina crystals. 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.
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.
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

Tabular alumina can be used as main component in alumina carbon fire brick, magnesia alumina carbon fire brick, magnesia spinel and alumina chrome refractory bricks, it also can be introduced into high alumina amorphous refractory materials such as rich alumina component. It can be widely used in iron and steel, casting, ceramics and other industries, even in iron and steel industry ,tabular alumina almost covers the whole process of ironmaking and steelmaking
