Metal oxide ultrafine particles were prepared by the hydrolysis of metal alkoxide in Aerosol OT (AOT) / isooctane and Tween85/isooctane reverse micelle systems. Monodispersed TiO<SUB>2</SUB> and ZrO<SUB>2</SUB> ultrafine particles less than 10 nm in diameter were successfully formed by the addition of titanium tetrabutoxide (TTB) or zirconium tetrabutoxide (ZTB) diluted with 1-butanol into reverse micelle solutions. The concentration and procedure of addition of feed alkoxide solution were found to be important factors in controlling the diameter and the number of particles. Particle diameter was controlled in the range of 2 to 8 nm by the number of successive additions of feed alkoxide solution of which the concentration was less than that of the solution used for nucleation.
