| Abstract: | Nanocrystalline anatase titanium dioxide powders have been prepared by hydrothermal treating the mixed solution of Ti(SO\-4)\-2 and urea.The cross experimental design was used in this study.Crystal phase,grain size and morphology of the as prepared powders were studied by XRD and TEM techniques.The influence of concentration of Ti(SO\-4)\-2 and urea, hydrothermal temperature and soak time were discussed in details.The as obtained TiO\-2 Powders was anatase,well degree of dispersion and 10 20 nm in mean grain size. The sequence of affecting factors is Concentration of Ti(SO\-4)\-2 and urea,temperature and soak time. |
| Keywords: | hydrothemal precipitation titanium dioxide nancorystalline powders |
