Abstract:

Phase relations in the Sr-Fe-Co-O system have been investigated at 1100 degrees C in air by X-ray powder diffraction on quenched samples. Solid solutions of the form SrFe1-xCoxO3-delta (0 <= x <= 0.7), Sr3Fe2-yCoyO7-delta (0 <= y <= 0.4) and Sr4Fe6-zCozO13 +/-delta (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 degrees C in air for the entire Sr-Fe-Co-O system has been constructed.
