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℃.
