1. Product Details
Cordierite Kiln post is made of Magnesium Aluminum Silicate which has very low thermal expansion and low thermal conductivity. Cordierite can withstand fast heating or cooling and is used when thermal shock is a concern traditionally used in top loading electric kilns. Cordierite kiln shelves are more susceptible to warping at higher temperatures with maximum firing temperature is cone 8. Shelves used up to cone 6 should be at least ¾” thick, and those used to a maximum of cone 10 should be at least 1” thick which makes them heavy. Cordierite has 13-25% porosity rate which will be a problem with glaze dripping (the glaze can easily penetrate the surface and melt into the shelf). Kiln wash should therefore be used to protect the surface. Cordierite kiln shelves are not recommended for salt or wood firings.

3. Application
Cordierite refractory kiln post applied to Sanitary ceramics
Our Cordierite refractory kiln post can offer high mechanical strength at high temperature, excellent heat stability, good distortion resistance at high temperature and oxidization resistance. It can be used in high class washing basin, high-class bowl and bowl urinal. Through the burning of 1300° C, it provides high enamel and high abrasion resistance. It can keep gloss and quality for 10 years. Our brand enjoy good reputation in this trade. We are improving our product and introducing green into our sales activity.
