SrTiO3 nanorods were synthesized in cetanyl trimethyl ammonium bromide(CTAB)reverse microemulsion containing CTAB,n-hexanol,n-octane and water with Ba(OH)2 as reactants.The effects of different conditions such as ω0 [ω0=n /nCTAB],aging time and the concentration of reactants on the formation of the nanorods were studied.Transmission electron microscope(TEM),electron diffraction(ED)and X-ray diffraction(XRD)were used to characterize the morphology and the structure of the synthesized nanorods.The results show that SrTiO3 nanorods with a length of 260～2 000 nm and a diameter of 50～100 nm belonging to single crystal are single cubic system.The molar ratio of Sr to Ti of products is 1.0 as determinded by ICP.
