Abstract: The preparation of TiO2 particles from H3TiO3 by using hydrothermal method was reported. The effects of H3TiO3, H4TiO4 and ions, for example: PO-4, Ac-, Zn2+, NH+4 and so on were studied. The results indicated that the phases and partical morphology of TiO2 were intimate relative to the structure of H3TiO3, PO-4 and other high valence or big anions could accelerate anatase formation of TiO2 and Zn2+, NH+4 or H4TiO4 were the promoter of rutile phase.

Key words: H3TiO3, hydrothermal method, TiO2 particles
