ZALYTabular Alumina is a pure sintered a-alumina material that has been fully
densified by rapid-sintering without the use of sintering aids at temperature in express
1900. 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 characteristic 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 products to be used as a filler in epoxy or resin
systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.
