alumina ceramics application

- Nov 29, 2017-

Alumina ceramics with low thermal expansion, high thermal conductivity, high mechanical strength and wear resistance to wait for an advantage, according to the alumina content can be divided into: high purity alumina ceramic, 99 porcelain, 95 porcelain, 95 porcelain, 75 porcelain, etc.; According to the main crystal phase difference can be divided into: corundum porcelain, corundum - mullite porcelain and mullite porcelain. Different categories of alumina ceramic products have different characteristics and application scope, such as: sintered corundum porcelain, normal temperature resistance to alkali and hydrofluoric acid, can resist erosion of metal and slag, room temperature can also be TiC, ZrC reduction, can react with water vapour long-standing, etc.

Other alumina ceramics also can be used as refractory materials, special machinery industry of wear-resistant parts and tool materials, used in electronic industry and other insulators, etc., according to the nature of the application, the properties of concrete depends on the composition and microstructure of alumina ceramics.
