• The process parameters of preparing nanosized titanium dioxide powders were systematically studied by electrochemical synthesis experiments at room temperature . the rutile phase and anatase phase powders were obtained in the sizes of 9.7nm and 9.2nm respectively, and the complete crystal powders were formed after calcined at 400 for two hours . in the process of experiments it was observed that the low current density resulted in rutile phase powders, while the addition of little amount of ions of sulfate promoted the formation of anatase phase powders
  在本实验条件下，小的电流密度有利于金红石相的生成，而少量硫酸根离子的引入对生成锐钛矿相粉体有利，调整电流密度大小和引入硫酸根离子的量，可以得金红石型和锐钛矿型的混合混体；研究无定型粉体，锐钛矿相粉体以及金红石型粉体随温度的粒径变化情况时发现，粉体在400以前晶粒长大相对缓慢，400以后晶粒粗化现象严重。
