Main Raw Materials

Alumina ceramics

Alumina Ceramic may be used in applications that require high elevated temperatures, High dielectric strength, excellent electrical resistance, wear or corrosion resistance, high temperature capability. High Electrical insulation.


 

Zirconia ceramics

Zirconia (ZrO2) is a unique advanced ceramic.

Products manufactured from zirconia powder exhibit superior mechanical properties such as high strength and flexibility.



 

Cordierite ceramics

The main chemical ingredient of cordierite ceramic is 2MgO·2Al2O3·5SiO2, main material is steatite, clay, alumina, feldspar, etc. Manufactured by normal ceramic technic, can be used for loop frame work, insulators of arc-resistance, element of composite materials, burnable nozzle of electrical insulators, etc.
