Pemasok yang Diaudit 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.
