Cordierite Ceramics

The main chemical ingredient of cordierite is 2MgOa 2Al2O3a 5SiO2,main material is steatitea claya aluminaa feldspar,etc.
Made by normal ceramic technic,such as dry press by press machine
They can be used for loop framework,insulators of arc-resistancea element of composite materialsa burnable nozzle of electrical insulators,and etc.
Color:white,light yellow and so on
