Refractory Corundum-mullite kiln tray for high temperature furnace
1. Product Description
Kiln tray is made of Corundum-mullite because it will survive thousands of heating and cooling cycles.
At Kam Tai all of our production is placed in Corundum-Mullite trays known as saggers to be used in the kiln during the firing cycle.
Small parts can be dry powder pressed. Large pieces are formed by slip casting.
Slip casting is a process where the ceramic material is mixed with water and poured into a
plaster mold. After a few hours the plaster draws off the water from the mix and the kiln tray or
other shape can be released from the mold. Parts are then dried and fired.
al shock resistance,high strength,no deformation, no shrinkage, no slag off,and other advantages.
It is widely used in high temperature furnace , like magnetic material and electronic ceramic and so on.
