Cordierite Ceramic - Magnesium Aluminum Silicate
What We Do
Physical Properties Of Associated Ceramics Cordierite
Cordierite is a magnesium aluminum silicate which possesses an extremely low thermal expansion and low thermal conductivity. Cordierite is used when thermal shock is a concern in the finished product. Cordierite is available in self- glazing form where higher strength, thermal shock, and dielectric strength is required. Applications include refractory shapes, welding tapes, heaters, thermocouples, and appliance insulators.
