Properties And Applications Of Tabular Alumina

Properties of sintered tabular alumina

1. Refractoriness ≥1800℃, its melting point is as high as 2050 ° C.

2. With coarse crystals and good development a Al2O3.The crystal structure greatly improves the creep resistance.

3. Plate crystal structure, small open porosity, low porosity, low water absorption; Internal containment gas,It has more holes and good thermal shock resistance and spalling resistance.

4. Because the consumption process does not add any additives, the purity is high, the volume stability is good, and the reburning shrinkage is relatively small.

The use of tabular alumina

As a new type of data, tabular alumina has been applied to the negative battery data, new ceramics, solar energy industry, seals, automobiles and other industries. Due to the hardness of emery ceramic, it can be prepared into a variety of grinding wheels, emery cloth, sandpaper and various abrasive materials, which are widely used in machining industry.

Tabular alumina material also has self-smooth and small friction coefficient, about half of cemented carbide, its thermal shock resistance, high elastic modulus characteristics in some central applications, such as used to make high-power laser mirror its performance is better than copper, due to low density, good rigidity, small deformation.
