用自行设计的、用于观测由透明均匀相中生成超微粒子的激光测试仪，对水解法制备纳米TiO2的过程进行了研究，并设定了一系列反应过程的内在参数，如成核温区△T，成核时间△t，反应成核浓度的参数I／I0等，并记录了这些参数及有关曲线，讨论了这些参数与最后产物性质的关系，研究了反应初始条件如浓度、酸度和阴离子等外部因子的改变对这些参数的影响，以及对最终产物性质（粒子大小、晶型结构）的影响，获得了金红石含量高，粒子直径在100nm的超细TiO2粉体．
The process of preparing nano-TiO2 by hydrolysis was studied with a laser tester designed by ourselves for observing the formation of ultrafine particles in a transparent homogeneous phase. The intrinsic parameters of a series of reactions such as nucleation temperature △ T, nucleation time △ t, reaction nucleation concentration parameter I / I0, etc .. These parameters and related curves were recorded. The relationship between these parameters and the properties of the final product was discussed. The initial reaction conditions such as concentration, acidity and Anion and other external factors on the impact of these parameters, as well as the final product properties (particle size, crystalline structure), obtained a high content of rutile, particle diameter of 100nm ultrafine TiO2 powder.
