A manufacturer of cordierite kiln furniture for the ceramics industry and other industrial heat-treatment applications, IPS Ceramics USA, recently launched two grades of cordierite: a porous cordierite (C520) for thermal shock resistance and use at higher temperatures, and a non-porous cordierite (C410).
Cordierite ceramics are well known for their exceptional resistance to thermal shock. They are often used for components that are subject to rapid thermal cycling, in applications where other ceramic materials would quickly crack or break. This can include anything from high-performance kiln furniture to catalytic converter honeycombs.
Cordierite products are fired close to 1,400°C (2,550°F) to give a material that is volume stable in service (temperatures up to 1,300°C/2,370°F). Products are thermally and electrically insulating and are often used as lead-in tubes or as supports for wire heating coils.
