“…The PLZT family was previously characterized by X-ray absorption, X-ray diffraction, Raman spectroscopy and impedance spectroscopy (Mesquita et al, 2010(Mesquita et al, , 2012(Mesquita et al, , 2014. The samples with x = 0.12 and 0.15 present a slight displacement of the dielectric permittivity (" 0 ) curve with frequency, and can therefore be characterized as relaxors (Mesquita et al, 2010).…”

This work reports the setting up of the X-ray diffraction and spectroscopy beamline at the Brazilian Synchrotron Light Laboratory for performing total scattering experiments to be analyzed by atomic pair distribution function (PDF) studies. The results of a PDF refinement for AlO standard are presented and compared with data acquired at a beamline of the Advanced Photon Source, where it is common to perform this type of experiment. A preliminary characterization of the PbLaZrTiO ferroelectric system, with x = 0.11, 0.12 and 0.15, is also shown.

“…It was very difficult for AFE ceramic to withstand a large external field. In order to tailor the dielectric properties, A-and B-site compositional modifications in PLZST system with a ABO 3 perovskite-structure were usually employed [10,11]. Recoverable energy density (W re ) of 61 J/cm 3 with an efficiency of 33 % had been demonstrated in AFE PLZT thin films under an applied field of &4.3 MV/cm [12].…”

Pb 0.97-x Ba x La 0.02 )(Zr 0.7 Sn 0.27 Ti 0.03 ) (0 \ x \ 0.08) antiferroelectric (AFE) ceramics were successfully fabricated by a solid state reaction, and the effect of barium (Ba) additions and temperature on the dielectric properties and energy storage performance were investigated. The ceramics with lower Ba content undergo two phase transitions during heating from room temperature to 300°C: orthorhombic (O)-rhombohedral (R)-cubic (C). With the increase of Ba content, dielectric constants increased and transition temperature decreased obviously. The ferroelectric phase was induced as the composition x increased from 0 to 0.08, however, which was not stable and transformed into AFE state upon heating, and then paraelectric phase, which was confirmed by DC field dependence of dielectric constant. The polarization sharply increased from 9.7 lC/cm 2 at 20°C to 24. 6lC/cm 2 at 100°C in (Pb 0.89 Ba 0.08 La 0.02 )(Zr 0.7 Sn 0.27 Ti 0.03 ) ceramic. As a result, the maximum recovered energy density of 2.1 J/cm 3 was obtained at 80°C, and the corresponding energy-storage efficiency was 76.5 %, which made this material a promising potential application in capacitors for pulsed power systems.
