Alumina has a high hardness and density, an Invar hardness of 9, slightly lower than diamond, a bulk density of generally greater than 3.5 g/m3, and some up to 4.0 g/m3. Alumina ceramics are classified into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, etc. according to the content of Al2O3. 99 alumina ceramic materials are used to make high temperature crucible, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings and ceramic seals. Parts, etc.; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts.
