Abstract: The monodispersed ultrafine TiO2 was prepared by the sol-gel method from Ti(OC4H9)4 in C6H6,CCl4 and C2H5OC2H5 respectively.The influences of heat treatment,molar ratio of water to Ti(OC4H9)4,and kinds of solvents have been examined.The spherial monodispersed anatase particles of 7nm and ultrafine tetragonal (40nm?10nm) and spherial (44nm) rutile were obtained.

Key words: titanium oxide, ultrafine particle, preparation, sol-gel method
