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.
