Tabular Aluminum Abrasives
- Brand Name: Luoyang Sunrise New Materials Co., Ltd.
- Tabular alumina is widely used in refractory materials. It provides high temperature resistance, thermal and chemical stability, abrasion resistance, high mechanical strength and excellent shock resistance.
- Tabular alumina is sintered calcined alumina. This high temperature process enables the alpha alumina crystals to grow into large grains, of a form resembling tablets, hence “tabular” alumina.
- Tabular alumina is made up of grains of alpha alumina with a diameter of 50 to 300 µm, formed by crystalline growth during sintering.
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 1900℃. Tabular Alumina has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm 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 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, kiln furniture and as a catalyst support. Ground Tabular Alumina is an excellent product to use as filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.
