| Hydrothermal Preparation of Anatase TiO_2 Nanopowder |
| DU Zuo juan; GU Ying ying （College of Chemistry and Chemical Engineering; Central South University; Hunan Changsha; 410083; China） |
| Abstract：TiO 2 nanopowder was prepared by hydrothermal method. The obtained powders were characterized by XRD and laser analytical techniques.The results showed that all powders were the single anatase titania and their primary particle size was about 50nm. The influences of crystallizing temperature and time were investigated. |
| Key words：hydrothermal method; nanopowwder; anatase titania |
