Description
Phase relations in the Sr-Fe-Co-O system have been investigated at 1100 deg. C in air by X-ray powder diffraction on quenched samples. Solid solutions of the form SrFe1-xCoxO3-δ (0≤x≤0.7), Sr3Fe2-yCoyO7-δ (0≤y≤0.4) and Sr4Fe6-zCozO13±δ (0≤z≤1.6) were prepared by solid-state reaction and by the sol-gel method. The structural parameters of single-phase samples were refined by the Rietveld profile method. The variation of the lattice parameters with composition has been determined for each solid solution and a cross-section of the phase diagram at 1100 deg. C in air for the entire Sr-Fe-Co-O system has been constructed. - Graphical abstract: Isobaric-isothermal cross-section of phase diagram of the Sr-Fe-Co-O system at 1100 deg. C in air
