Cordierite Ceramic Honeycomb Description
Cordierite ceramic honeycomb is made of cordierite ceramic. Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties. Cordierite also has low thermal conductivity and thermal expansion, while also being cost-effective. Often used as a structural ceramic for kiln furniture applications, it also finds uses in other applications where rapid temperature changes take place.
Cordierite Ceramic Honeycomb Advantages
- Excellent thermal shock properties
- Low thermal conductivity and thermal expansion
- Good mechanical strength
- Can be used up to approximately 1200°C
- Outstanding crack-resistance
