Abstract: Influencing factors during the phase transition of TiO2 from anatase to rutile were summarized.The effects and action mechanism of temperature and additive control and adjustment on the phase transition of TiO2 from anatase to rutile were also investigated in detail. Results showed that:temperature control and adjustment can promote TiO2 phase change directly and effectively;when the ion radius of the doped metal ions,such as Fe3+,V4+,and Ce4+ were similar to Ti4+,the melting point of metal oxides,such as V2O5 and SnO2 was lower than that of the TiO2,and low valence anions,such as Cl- and F- with low volume,they all could promote the phase transition of anatase to rutile.
