摘要/Abstract

摘要： 采用高温固相合成法制备出掺杂Y³⁺的BaCeO₃电解质BaCe_1-xY_xO_3-δ（x=0.10~0.30). XRD谱分析结果表明，样品均为正交钙钛矿结构；氧空位、缺陷缔合和固深度均对样品的质子电导率与掺杂浓度有一定影响.

关键词: XRD谱, 固溶度, 氧空位, 缺陷缔合

Abstract: We used high temperature solid state reaction method for synthesizing Y³⁺-doped BaCeO₃ solid electrolyte BaCe_1-xY_xO_3-δ (x=0.10~0.30). X-ray diffraction analysis shows that the samples crystallized in a perovskite phase. The non-linear relationship between proton conductivity and Y3+ content of sample is closely related with the oxygen vacancy, the defect association and the solid solubility of Y.

Key words: XRD, solid solubility, oxygen vacancy, defect association
