【Abstract】 The multi-level experiments were made of titanium liquid, TX-10, 6501, SJY, pH value and temperature, and the particle diameter of the final nanometer TiO2 product was tested by using precipitating method to prepare nanometer TiO2 and using even design U7(76) to arrange the experiments. After regression analysis with computer, the appropriate mathematical model was made, the influence of every factor on the preparation of nanometer TiO2 was assessed and the best factor and level combination were received.更多还原
