Study on the Surface Status and Agglomeration of TiO2 Nano-Powder
纳米TiO2粉体颗粒的表面特征与团聚状态

The TiO2 nano-powder was prepared by the precipitation of Ti(OC4H9)4 in aqueous solution.By using FT-IR, as well as potential techniques, it was found that the preparing process and thepost-process affect the suffice status of TiO2 nancy powder. The factor to affect the agglomerationwas analyzied theoretically, so that the best process to control the agglomeration of nano powderswas found.
