Abstract：The different particle size of nano-sized Y2O3 spherical powders were successfully prepared by homogeneous precipitation method,with different suffactants,urea as the precipitating agent and Y(NO3)3 as the yttrium source.The factors such as the reaction time,reaction temperature,reactants concentration,surfactant type and dosage on the morphology and particle size of Y2O3 powders were studied.The samples were characterized by laser particle size analyzer and scanning electron microscopy (SEM).The results show that the reaction time,reactants concentration,surfactants,reaction temperature affect the dispersant and particle size of the powders,the mixed using of CTAB and PEG-4000 reduce the particle size of Y2O3 significantly and improve dispersion of particles,and the particle size of Y2O3 powders is about 50 nm.
