AbstractMixed conducting ceramic oxide SrFeCo0.5Oy powders were prepared by a conventional solid-state reaction method and two types of hybrid microwave heating methods. XRD, SEM/EDS (energy-dispersive spectroscopy), and TEM/EDX (energy-dispersive X-ray microanalysis) were used to characterize the products. The conventional heated sample is a three-phase mixture composed of a predominant orthorhombic Sr-4(Fe1-xCox)(6)O13+/-delta phase, a cubic perovskite SrFe1-xCoxO3-delta phase, and a CoO phase. Phase components of the direct hybrid heated samples are similar to those of the conventional heated sample, except that its predominant phase is a cubic perovskite SrFe1-xCoxO3-delta phase other than the orthorhombic Sr-4(Fe1-xCox)(6)O13+/-delta phase. The indirect hybrid heated sample is mainly composed of a cubic perovskite Sr(Fe,Co)(1.5)O-y phase, with a trace amount of orthorhombic phase and spinel (Fe,Co) oxides. The cobalt content of the Sr(Fe,Co)(1.5)O-y phase is much higher than that of the SrFe1-xCoxO3-delta phase. Particle size distribution of the conventional heated sample is very wide. The indirect hybrid heated sample has a relatively narrow particle size distribution, with an average particle size of 3-4 mum, but the particles stick to form agglomerates. The morphology of the direct hybrid heated sample is similar to that of the conventional heated sample, except that submicrometer grade particles were rarely observed.
