1. Cordierite ceramics:
Cordierite ceramic is a magnesium aluminum silicate material that has been widely used in applications where thermal shock resistance is important. Cordierite ceramic is also useful because it has a low thermal expansion and good electrical insulation compared to other ceramic materials.
Physical Properties:
*Good thermal shock resistance
*Low thermal expansion
*Low thermal conductivity
*High dielectric strength
Applications:
*Household Appliances (Insulators)
*Heating element supports
*Refractory supports in ovens or kilns
*Thermocouples
*Electrical Insulators
2. Mullite ceramic (Pythagoras):
Mullite is a good, low cost refractory ceramic with a nominal composition of 3Al2O3•2SiO2. It has excellent high temperature properties with improved thermal shock and thermal stress resistance owing to the low thermal expansion, good strength and interlocking grain structure.
