Abstract

Solid solution series of La_1-ySr_yCo _1-xFe_xO_3-δ were extensively studied in the past as cathode materials for solid oxide fuel cells. However, the crystal structure behavior of La_1-ySr_yCo_1-xFe _xO_3-δ solid solution series when La-ions are replaced with another rare-earth ion or metallic alkaline earth metal is at present not fully understood. Here we report X-ray powder diffraction measurements performed on samples of the Sm_0.8Sr_0.2Co _1-xFe_xO_3-δ solid solution series. This study demonstrates that the average A-cation radius, as well as the Fe content (x), affects the structural modification of the A_1-ySr _yCo_1-xFe_xO_3+δ solid solution series significantly.
