High Temperature Cordierite Kiln Shelves Fish Shape For Ceramic Bowl

Refractory high temperature Cordierite fish kiln shelf for ceramic bowl

1. Introduction 

Cordierite has excellent thermal shock resistance, good strength and can be formed by pressing, extruding, casting and vibrating into complex shapes. Cordierite mullite kiln furniture is widely used in porcelain, heavy clay, glass panel, powder metallurgy, magnetic materials, green energy, food, glass, abrasives, iron and steel, mining and aerospace engineering.
Besides its use as kiln furniture, it is also extensively used in kiln structures and kiln car system, where it is combined with ceramic fiber to achieve the aims of improving fuel efficiency and avoiding contamination.

A simple firing to 1300C (about cone 11 and within the reach of many ordinary kilns) and soaked may produce some crystal development. However firing (actually sintering) at 1400C+ with significant soaking time is needed for the best results. Thermal expansion measuring equipment is needed to determine if your firing is actually developing the crystal matrix or not.

If you are planning to rotate / flip your shelves over every few firing, you'll need to scrape and grind all the kiln wash from the bottom side first. Failing to do so will cause kiln wash particles to fall into the pots below and ruin the glaze effect.

2. Advantages
Excellent energy savings
Lighter weight and higher load capacity
Excellent distortion resistance at high temperature
Suitable for faster firings with better bearing capacity for hot and cold extremes

3. Application 

Cordierite Kiln shelf is widely used to sinter pottery , ceramic insulator and so on.Using temperature can not be over 1300 ℃
