Paper Title:
Structural Analysis of Multiphase La1-XSrxCo1-XFexO3-δ
  Abstract

Multiphase La1-xSrxFe1-yCoyO3-δ has been synthesized by sol-gel method and characterized by powder X-diffraction. Structure refinements of multiphase were undertaken to analyze compositions of compounds, and structure parameters were determined by Rietveld method, respectively. It was found that products were easier to be prepared in the condition of a precursor dealed with by high-speed disintegrator, and products synthesized at 1173K were composed of two phases of which La0.75Sr0.25Co0.2Fe0.8O3-δ is an orthorhombic structure with space group Pbnm and La0.46Sr0.54Co0.2Fe0.8O3-δ trigonal structure with space group R-3c. Structure geometry becomes more regular with increasing Sr content.
