This paper mainly discuss the TiO2 on synthesizing the crystal structure of the cordierite, crystallinity, grain size, sintering properties. Use the software of X 'Pert plus to fit the XRD diagram, analyzing the properties of the crystallization, with the Scherrer formula to calculate the size of the cordierite in the specimen, discussing the TiO2 on synthesizing the crystal structure of the cordierite, the influence of microcosmic structure and sintering property can be carried out analysis with SEM. The results show that moderate introducing TiO2 in the process of the cordierite synthesis can easily make the crystal defects, but it can reduce the diffusion resistance of the particle, improve the particle diffusing speed and make the crystallinity of crystallization phase and grain size increase in sample. Due to the radius of the solute ion are greater than the radius of the solvents ion and to some degree the "inflation" function of the clearance of ions can also promotes the volume of the crystal cell. Introduction of excessive TiO2, the density of the sample and the sintering property is better, but the property of crystallization is declined.
