Cordierite mullite kiln furniture
Detailed Product Description
The products showing in the above photo are sagger and base plate.
Kiln furnitures for kilns are high-grade,selected mullite and cordierite as raw materials, adopted advanced technology, including slab, sagger, muffle plate, rack, base plate, strut. The refractoriness of the kiln furniture (combined mullite with cordierite) is better than cordierite, the thermal stability is superior compared with mullite corundum material.
Characteristics:
Low thermal expansivity
Resistance to thermal shocks
No abrupt failure
Nonoxidizable
Antifouling
