Hydrothermal Synthesis and Morphology Evolution of Perovskite PbTiO3 Crystals with Different Lead Sources

  Perovskite lead titanate crystals with various morphologies were successfully synthesized via a hydrothermal reaction route with different lead sources.X-ray diffraction (XRD),Raman spectroscopy,scanning electron microscopy (SEM),transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were employed to characterize the phase composition and the morphology of the synthesized products.In order to investigate the effect of the lead source on the phase formation and morphology evolution of the synthesized pervoskite PbTiO3 crystals,PbO,PbF2,PbSO4 and Pb(CH3COO)3 ·3H2O,were used as starting precursor lead source introduced into the hydrothermal reaction system,respectively.Accordingly,perovskite PbTiO3 brken cubes,irregular particles,cubic particles,and microplates were obtained,respectively.Based on the experimental results,the effect of lead source was simply discussed.
