A novel surfactant-modulated precipitation method is proposed to produce pure perovskite Pb(Sc1/2Nb1/2)O3 (PSN) nanopowders at a low temperature of 700 °C. The samples were characterized by XRD, SEM, TEM, and HRTEM, respectively. The results indicate that the powders exhibit a granular shape of 80 nm in diameter. It is believed that the nanosize of as-prepared PSN powders is dependent on the well-dispersed...
