摘要：
Double perovskite-type BixSr2-xCo0.5Fe1.5O6-delta (BiSCF) oxides with various A-site (x = 0.6, 0.7, 0.8, designated as BiSCF06, BiSCF07, BiSCF08, respectively) have been synthesized by a solid-state reaction technique, and investigated on their structure properties of perovskite powder for application of inteunediate-temperature solid oxide fuel cells (IT-SOFCs) purpose with related to the calcination temperatures at 950, 1000 and 1050 degrees C. The crystal structure of the BiSCF powder was analyzed by X-ray diffractometer (XRD), and determined by Rietveld refinement. The results show that BiSCF07 powder which calcined at 950 degrees C shows the best structure of cubic perovskite with space group Pm-3m and a lowest impurity at room temperature indicated structure stability and offers a higher mobility of oxygen vacancies. Based on this result, BiSCF07 powder has a potential to be developed as cathode for IT-SOFCs applications.
