Abstract

Antiferroelectric analogous (Pb_0.92Sr_0.05La_0.02)(Zr_0.7Sn_0.25Ti_0.05)O₃ (PSLZSnT) ceramics were prepared by the solid-state sintering method by introducing a Y₂O₃-coating via the self-combustion method. The synthesized Y₂O₃-doped PSLZSnT ceramics present pseudo-cubic structure and rather uniform microstructural morphology accompanied by relatively small grain size. Excellent energy-storage performance is obtained in the Y₂O₃-doped PSLZSnT ceramics, in which the value of the energy-storage density presents a linearly increasing trend within the electric field measurement range. Such excellent performance is considered as relating to the rather pure perovskite structure, high relative density accompanied by relatively small grain size, and the antiferroelectric-like polarization-electric field behavior.

Keywords: PSLZSnT antiferroelectric-like ceramics; energy-storage density; oxide doping; perovskite structure; self-combustion method.
