Abstract

Pure-perovskite 0.64Pb(N_1/3Nb_2/3)O ₃-0.36PbTiO₃ (PNN-PT) powder has been successfully synthesized by only one-step calcination using a coating method. SEM photograph shows that PNN-PT powder with the size of 2-4 μm is cubic and well dispersed. Based on X-ray diffraction analysis, solid-state reactions in the process of calcination in PbO-Nb₂O₅-TiO₂-NiO system are investigated. In comparison with conventional solid state method, the single-calcination synthesis mechanism of pyrochlore-free lead-based niobate ferroelectrics using a coating method is tentatively proposed. A typical coating structure of Ni precipitate-coated Nb₂O₅ powder facilitates the formation of perovskite PNN-PT phase at a relatively low calcination temperature, resulting in the successful synthesis of pyrochlore-free PNN-PT powder in one-step calcination at 900°C.
