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 ℃
