Cordierite ceramic(iolite ceramic): Main crystal phase is 2MgO.2Al2O3.5SiO2, often when the absorbent ceramic, ceramic rods, porous ceramic, porous ceramic filter, low thermal expansion coefficient, good thermal stability, for the production of the heater plate, thermocouple ceramic pieces of insulation, kiln furniture and other hot and cold rapid degeneration requirements for high places, can also be used as the coil skeleton, arc resistance effects of electrically insulating ceramic material, composite material base material, electric insulating device of burner nozzle.
we can make many kinds of technical ceramic according to your requirement
