Abstract In order to reveal the influence of Si impurity elements on the phase transformation mechanism of titanium dioxide, rutile intermediates of H₂TiO₃ and H₄SiO₄ doped with Si (10%) were prepared by TiCl₄ hydrolysis method. The high temperature phase transition of TiO₂ under the effect of doped-Si was studied by DTA-DTG and XRD. As a result, it was found that the Si(10%) doped TiO₂ was transformed from an amorphous structure to an anatase phase at 650℃, and changed from an anatase to a rutile phase at 1 000℃. The results show that compared with the pure TiO₂ phase transition temperature, the doping of Si inhibits the transformation temperature from amorphous to anatase and anatase to rutile. At the same time, it was found that with the increase of the high temperature time, the crystallinity of the same crystal form of titanium dioxide changes.
