Cordierite Ceramic Tubes Description
Cordierite Ceramic Tubes are manufactured from cordierite ceramic. Cordierite ceramic is a type of magnesium‐aluminium silicate that exhibits good thermal shock resistance. It also features low thermal conductivity and low thermal expansion. It is cost‐effective. It is frequently employed as a structural ceramic for fuel aids and is used in other applications where rapid temperature fluctuations occur.
Properties of Cordierite Ceramic Tubes
- High thermal shock resistance
- Low thermal conductivity and low thermal expansion
- Measured mechanical strength
- Suitable for use up to approximately 1 200°C
- High resistance to cracking
