Abstract: The monodispersed nano-Sb₂O₃ was prepared from SbCl₃ as raw material by alcoholysis，hydrolysis and treatment with surfactants.Various factors and levels in the preparation of monodispersed Sb₂O₃ nanoparticles were studied with changing factors and orthogonal test. The effects of the type and amount of surfactants as dispersant on the size and morphology were also studied with TEM and sedimentation.The results showed that the optimum conditions of preparing monodispersed Sb₂O₃ nanoparticles were concentration of SbCl₃ in CH₃CH₂OH 0.17 g•ml^-1，reaction temperature 318 K and reaction time 1 h.The surfactants，as shown in the experiments，were important to disperse and keep Sb₂O₃ nanoparticles.The monodispersed nano-Sb₂O₃ of about 25 nm could be obtained by treating 1 g nano-Sb₂O₃ with 1.0 ml PEG or 0.3 g CTAB.
