The crystal structure and chemical composition of Ba0. 5Sr0. 5Co0. 8Fe0. 2O3-δ bulk samples and powders were studied after heat treatments between 700 C and 1000 C. X-ray diffractometry (XRD) and in addition transmission electron microscopy (TEM) combined with energy dispersive X-ray spectroscopy (EDXS) was applied to analyze the properties of individual grains. Besides the cubic perovskite phase a hexagonal phase and an additional, not yet clearly identified phase was found at temperatures below 900 C.
