The hydrothermal reaction behavior of rich-titanium material in the hot Na OH solution was studied in this paper,and the effects of alkali concentration,temperature,reaction time on the conversion rate of TiO2 were investigated by Box-Behnken central composite design and response surface analysis. The results show that the highest product conversion rate can be reached under alkali concentration 25%,temperature 186 ℃ and reaction time 4 hours. The conversion rate of product under optimal conditions was verified. The morphology and phase characterization of reaction products were analyzed by scanning electron microscopy （SEM） and X-ray powder diffraction （XRD）. Different reaction products were obtained under various conditions,and the morphologies change gradually with different conditions.
