Hybrid Heating Synthesis of Mixed Conducting Oxides SrFeCo_(0.5)O_(3-x) Ceramic Powder

Mixed conducting ceramic oxide SrFeCo 0.5 O 3- x powders were prepared by hybrid heating (microwave+resistance heating) and solid state reaction method. Powder X ray diffraction and scanning electron microscopy coupled with EDX were used to characterize and analyze phase component, morphology and chemical composition of the powders synthesized by two methods. The hybrid eating has the same phase components as that of solid state method, but the proportion of phase components is different. The predominant phase is perovskite in the hybrid heating sample, whereas the orthorhombic phase as a major phase is observed in solid state reaction sample. The powder prepared by hybrid heating has a uniform size distribution and better crystallinity.
