Cordierite Electronic Ceramic Parts Insulator Ceramic
Cordierite ceramic insulator
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, and etc.
Cordierite-based ceramics are extensively used in important industrial applications such as micro electronics, refractory products, heat exchanger for gas turbines ,thermal shock-resistant table ware, catalyst supports ,and porous ceramics .Low-expansion cordierite is suitable for being applied at high temperature circumstance where a good thermal shock resistance is required .
Small cordierite parts can be dry powder pressed. Large cordierite pieces are formed by slip casting.
Slip casting is a process where the ceramic material is mixed with water and poured into a
plaster mold. After a few hours the plaster draws off the water from the mix and the sagger or
other shape can be released from the mold. Parts are then dried and fired.
