Tabular Alumina Ball

Aluminum oxide 99.3%Min Sintered White Tabular alumina for refractory purging plugs

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 1900°C.

Tabular Alumina has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200µm length.

Quantity:
  • Ball - UTA2, UTA3,UTA5
  • UNION

Product Description

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 has extremely high refractoriness, high mechanical strength and abrasion resistance, very good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion.

Tabular Alumina is the aggregate of choice in unshaped and shaped high performance refractory. It is used in a variety of industries such as steel, foundry, petrochemical, ceramic and incineration. Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support.

Ground Tabular Alumina is a excellent product to used as a filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.
