In this study, high purity nano-TiO2 was prepared from Panzhihua ilmenite using sulfuric acid-decomposition by liquid phase method. The effects of H2SO4 molar volume, reaction time, initial pre-heating temperature and H2SO4 concentration on the decomposition rate of ilmenite were investigated in detail. The results showed that the decomposition rate reached 95.21% under the optimal conditions. The...
