Cordierite Ceramic Tubes

Cordierite ceramic tube is made of cordierite ceramic. Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties. Cordierite ceramic tube also has low thermal conductivity and thermal expansion, while also being cost-effective. It is often used as a structural ceramic for kiln furniture applications, and it also finds uses in other applications where rapid temperature changes take place.

Product Features:

1) Excellent thermal shock resistance and stability at high working temperature 1300C
2) Light deadweight, good loading capacity
3) High strength and high resistance to deformation at high temperature
4) Significantly saves energy, the fuel consumption can be reduced by 25-50%
5) Good heat distribution and thermal shock resistance
