The typical product properties are based upon the actual averages from product data.The Min/Max data show our standard product specification data for these products.other sizes re available upon request.

Packaging:25kg paper bags on 1.5mt pallets.

Tabular Alumina is a pure sintered a-alumina material that has been fully densifed by rapid-sintering without the use of sintering aids at temperatures in excess of 1800℃.Tabular Alumina has characteristic large,well developed hexagonal tablet shaped a-alumina crystals of up to 200um 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.Tabular alumina has extremely high refractoriness,high mechanical strenght and abrasion resitance,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 refractories.it is used in a variely 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 conducivity or abrasion resistance is desired.
