Refractory Cordierite Kiln Post For Firing , Good Thermal Shock
Resistance
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.
Our Cordierite refractory kiln post can offer good heat stability,
high mechanical strength at high temperature, excellent thermal
stability and distortion resistance at high temperature. Cordierite
kiln post can be used in daily ceramics widely, such as sanitary
ceramic, daily ceramic, art ceramic, pottery ,porcelain tableware
and so on. Through the burning of 1400° C, its products can offer
mild, bright and white enamel feeling. Our Cordierite refractory
kiln post can save the energy and increase the volume of kiln;
Therefore it can increase the efficiency and economy. At the same
time, our Cordierite refractory kiln post is harmless to
environment. Through quality product and honest cooperation, we
will bring you benefit and trust.

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.
