Brief
Tabular Alumina has excellent light transmission, corrosion resistance and abrasioin ratio.
Detailed description
Tabular Alumina
1. Application: Tabular Alumina is used in a variety of industries such us steel, foundry, petrochemical ceramic and incineration. Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support. Ground TA 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.
2. Introduction:
Our new product tabular alumina (TA) is made of pure sintered α-alumina of large, well developed hexagonal tablet shaped α-alumina crystals of up to 200µm length.
TA has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900℃.
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.
