Spherical amorphous monodispersed titanium dioxide particles were synthesized by hydrolysis of titanium-tetra-ethoxide (Ti(OC2H5)4) in dilute ethanol solution and were hydrothermally treated using an autoclave. The amorphous monodispersed titanium dioxide particle were crystallized and many nano-sized particles of anatase single crystal produced in the particle by the hydrothermal treatment. The internal microstructure of the hydrothermally treated monodispersed titanium dioxide particle was homogeneous. The growth mechanism of the nano-sized anatase single crystal particles was discussed and a dissolution-reprecipitation mechanism was proposed.
