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.

1. The main goal is to reduce the thermal expansion coefficient of cordierite and improve the thermal effect of anisotropy, while ignoring the research on its strength, stiffness and hardness. For example, there are basically no studies on the ion doping modification reported. Research its mechanical properties;

2. The main goal is to increase the strength of cordierite by strengthening and toughening, while ignoring the influence of the second relative ceramic thermal properties. For example, using SiC and AlN as additives can increase the strength of ceramics, but its thermal expansion coefficient is not affected. No report.
