“…(rhombohedral phase) and a wide band at ~580 cm-1 in the infrared spectrum, could be attributed to the characteristic signal of perovskites due to the Co-O asymmetric stretching of the CoO6 octahedra.However, the X-ray diffraction powder patterns showed Sr6Co5O15 phase and small amounts of SrCO3 and Co3O4 as secondary phases, also corroborated by FT-IR. …”
