Abstract:

Cordierite (Mg2Al4Si5O18) ceramics are widely used in the fields of structural ceramics, catalyst carriers,honeycomb ceramics and electronic materials owing to its excellent mechanical properties,low dielectric constant and low thermal expansion coefficient.In recent years,researchers have made significant progress in cordierite crystal structure and improving the density.In this paper,state-of-the-art research status of cordierite ceramics are reviewed including the crystal structure and densification of cordierite ceramics.On this basis,the issues in the preparation and application of cordierite ceramics are pointed out and the development trend of dense cordierite ceramics is prospected.
