Cordierite
Cordierite impresses with its particularly beneficial temperature characteristics. This means: Heat reactions hardly have any effect on a ceramic which is usually made from the natural raw materials of soapstone, clay, kaolin and corundum.
The material properties provide clear-cut confirmation:
- Very slight thermal expansion
- Thus an extremely high resistance to thermal shocks
Ongoing, typical examples of use:
- Spark protection flats
- Expansion bars for thermostats
- Burner nozzles for car supplementary heating systems
- Heater conductor carriers for sophisticated thermal operations
