Product Description

White&Yellow Refractory Cordierite High Temperature Electric Heating Element Bobbin Heater

Cordierite Ceramic Bobbin (Head and Bottom) is mainly used as Ceramic Bobbin Heater.

Cordierite 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.

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.
