CC2288 Cordierite Tube, Silicate Tube

Cordierite Tube Description

Cordierite ceramic tube 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. 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.

Advanced Ceramic Materials (ACM) is a trustworthy supplier of cordierite ceramic products.

Cordierite Tube Characteristics

* Excellent thermal shock properties
* Low thermal conductivity and thermal expansion
* Good mechanical strength
* Can be used up to approximately 1200°C
* Outstanding crack-resistance
