cordierite mullite tray
- Introduction of Cordierite-Mullite
Cordierite-Mullite kiln furniture is composed of cordierite, mullite and glass phase. Due to high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite kiln furniture formed good property of excellent thermal shock resistance. Cordierite-Mullite kiln furniture can be used at 1350℃, which makes it can fulfill the production demands of most ceramic industry.
