Objective： To study hydrolysis parameters of titaniam dioxide （TiO2 ） prepared from high titanium slag. Mothods： Titanium solution prepared from high titanium slag as the raw material, TiO2 was prepared by self-growing inoculating crystal with tita- nium solution. The influence of operating conditions of feed fluid rate, base water volume, heating temperature and heating time on the rate of hydrolysis of titanium solution were investigated. Results： The optimum operating conditions were obtained as base water volume of 67 ml （6：1 ）, hydrolysis temperature of 100 ℃, feed fluid rate of 40 ml/min and heating time of 90 min. Conclusion： The results from the study can be used as a guideline in industry.
