摘要

Pb0.97La0.02(Zr0.80Sn0.12Ti0.08)O3 ceramic system was synthesized via the conventional solid-state reaction method. Structural, dielectric properties and energy storage behavior were investigated. The structural analyses were carried out from the X-ray diffraction technique, including the Rietveld refinement method, and Scanning Electronic Microscopy. Results confirmed the formation of the perovskite structure, showing the coexistence of two antiferroelectric phases governed by the tetragonal (P4mm) and orthorhombic (Pba2) symmetries. The dielectric analysis revealed a single dielectric anomaly, which was associated to the antiferroelectric-paraelectric phase transition. The energy storage performance was investigated from the electric field dependence of the polarization (P−E curves), at 60 kV/cm, covering a wide temperature range. The obtained results revealed a ceramic material with suitable properties for energy storage applications. The temperature dependence of the switching electric fields was also analyzed.
