Abstract

The monodisperse spherical particles of TiO₂ were prepared by sol-gel process in mixed solvents at low temperature. The TEM, SEM, and size distribution analysis showed that the size variation of as-synthesized spherical TiO₂ colloidal particles is within 5% and the polyindex is 0.013. The thermal analysis clearly demonstrated that as-synthesized particles were hydrous amorphous TiO₂. The structure of the TiO₂ colloids after annealed at different temperatures were determined by XRD. The results showed that the phase transition from amorphous to anatase occurred at a temperature around 600 °C and both rutile and anatase appeared at 900 °C.
