Cordierite-Mullite kiln furniture is composed of cordierite, mullite and glass phase. Due to the high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite kiln furniture has excellent thermal shock resistance,long service time,can be safety used at temperature below 1350℃.
Cordierite Mullite Kiln Furniture Features:
1. Good thermal conductivity 2. Good high temperature strength 3. Wear resistant and erosion resistant 4. Good thermal shock resistance 5. Good corrosion resistance 6. Good oxidation resistance 7. Not easy in deformation and cracking
