Preparation and property of oxygen permeation membranes Ca0.5Sr0.5CoxFe1-xO3-δ

    摘要
  • 摘要: 在1000~1200℃温度范围内用固相反应法合成钙铁矿结构的材料Ca0.5Sr0.5COxFe1-xO3-δ,用XRD对合成的试样进行了物相分析,探讨合适的烧成制度.用直流四电极法对样品进行了电导率测量.结果显示,制得的Ca0.5Sr0.5Co0.8Fe0.2O3-δ样品为单相产物,具有良好的电性能,是一种有应用前景的混合导体材料.

     

    Abstract: A brownmillerite-type of Ca0.5Sr0.5CoxFe1-xO3-δ was prepared using a solid-state reaction method in the temperature range of 1000 to 1200℃. The structure of the material was characterized by means of XRD to seek for a suitable sintering procedure. The conductivities were tested by means of DC four probes. The experimental result shows that Ca0.5Sr0.5Co0.8Fe0.2O1-δ is a material of promising application, which has a single-phase structure and good electrical performance.
