Advanced ceramics is different from traditional ceramics.Traditional ceramics include clay products, silicate glass and cement,but advanced ceramics are ceramic products made from materials like aluminum oxide (Al2O3), zirconium oxide(ZrO2), silicon carbide(SiC), silicon nitride(Si3N4), boron carbide(B4C) etc. In general, this kind of ceramic products have the following properties:


*Hard (wear resistant)

*Resistant to plastic deformation

*Resistant to high temperatures

*Good corrosion resistance

*Low thermal conductivity

*Low electrical conductivity

Additionally, some ceramics exhibit other properties like high thermal conductivity or high electrical conductivity etc. The combination of these properties means that ceramics can provide:


*High wear resistance with low density

*Wear resistance in corrosive environments

*Corrosion resistance at high temperatures

Because of these special properties,the application of advanced ceramic is very wide.For example:


1.Seal rings

2.Medical prostheses

3.Laser tubes

4.Electronic substrates

5.Ballistic armour

6.Thermocouple tubes

7.Electrical insulators

8.Grinding media

9.Threadguides

10.Wear components
