摘 要:Lead lanthanum zirconate stannate titanate(PLZST)powders with homogeneous composition were synthesized at a relatively low temperature of 650°C by a citrate process based on the Pechini method. Clear aqueous solutions were prepared from inorganic salts,and citric acid was added as a chelating agent to attain precursor sols.Dried gel-precursors were calcined at different temperatures for various time.The perovskites powders were obtained at 650°C for 1 hour.XRD and SEM results show that the powders were single-phase and ultrafine particles.
