1) High-purity chemical raw materials (MgO, Al2O3 and SiO2) are used to synthesize cordierite at high temperature. In order to obtain cordierite refractories with high cordierite content and a certain porosity, the researchers used X-ray diffractometer, scanning electron microscope and thermal dilatometer The effects of adding CeO2 on the phase composition and properties of cordierite ceramics were studied when cordierite ceramics were prepared from oxide powders (MgO, Al2O3 and SiO2), and the mechanism of CeO2 in the sintering process was analyzed. The advantage of this process is that the purity of the synthesized product is high, but the disadvantage is that the process cost is high and the reaction temperature

This should be selected according to the requirements of cordierite and the temperature. If the temperature is not too high, use cordierite. When choosing cordierite, the place of origin is the main factor

Because cordierite has good adsorption properties, good matching with various catalyst active components, thin pore walls and large geometric surface area, it can be used to prepare porous materials such as honeycomb ceramics and foam ceramics.
