High Bulk Density Tabular Alumina

タイトルまたは説明

Tabular Alumina
 
Tabular Alumina(TA) is a pure sintered a α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess ***0ºC. TA has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to **0μm 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. TA 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. TA 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, kiln furniture and as a catalyst support. Ground TA is an excellent product to use as filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.
