Abstract
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 performance, which arouse from the combined effects of both precipitant TMAH and surfactant CTAB. The mechanism of the formation of the pure perovskite PSN nanopowders is discussed in detail. Our method is expected to create a new, low-cost route to produce the promising nanopowders of multi-component perovskite systems.
