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.
