Mixed conducting perovskites and their solid state chemistry
The presented work comprises six original research articles on the solid state chemistry of selected cubic perovskite-type oxides. Cobalt containing mixed conducting perovskite-type materials like (Ba0.5Sr0.5)(Co0.8Fe0.2)O3-d (BSCF) show exceptionally high oxygen fluxes. But serious long-term stability problems in the intermediate temperature (IT) range of 500-800 °C and a high coefficient of thermal expansion due to the flexible redox behavior of ...
