Abstract

Antiferroelectric analogous (PbSrLa)(ZrSnTi)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.

摘要

通过自燃烧法引入Y₂O₃涂层，采用固态烧结法制备了反铁电类似物(PbSrLa)(ZrSnTi)O₃(PSLZSnT)陶瓷。合成的Y₂O₃掺杂PSLZSnT陶瓷呈现准立方结构，微观结构形态相当均匀，晶粒尺寸相对较小。Y₂O₃掺杂PSLZSnT陶瓷具有优异的储能性能，在电场测量范围内，储能密度值呈线性增加趋势。这种优异的性能被认为与相当纯的钙钛矿结构、高相对密度以及相对较小的晶粒尺寸和类反铁电极化-电场行为有关。
