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.

Physical Properties:
*Good thermal shock and stress resistance
*Low thermal conductivity
*Good strength
*Wear resistant
*Usable to high temperatures

Applications:
Radiant heating tubes
Furnace liners
Electrical insulators
