Cordierite Powder is used to manufacture kiln furniture, molded honeycomb-like catalyst supports in auto emission reduction devices, thick films, porous ceramics, feed-thru insulators, vitrified ceramics, high-frequency insulators, high-performance resistors, special furnace shapes, heating element supports, exhaust catalyst supports, burner tubes, refractory setters, and substrates.
Cordierite is not a very common mineral but is important as a component of glass-ceramic materials used in applications where the material must have minimal thermal expansion (eg cooker hobs).
