Abstract:

Phase equilibria in the La-Co-Fe-O system are studied at 1100degreesC in air using samples prepared by the citrate, nitrate, and conventional ceramic routes. The stability regions and structures of solid solutions in the La-Co-Fe-O system are determined by x-ray powder diffraction: LaCol-yFeyO3-delta(0 < y less than or equal to 0.25, sp. gr R3c; 0.775 less than or equal to y < 1,sp. gr. Pbnm), Co1-y FeyO(0<0.13, NaCl-type structure, sp. gr. Fm3m), and Fe3-x CoxO4(0.84less than or equal to x less than or equal to 1.38, sp. gr. Fd3m). The structural parameters of phase-pure solid solutions are determined by the Rietveld method. The composition dependences of lattice parameters are presented for LaCol-yFeyO3-delta(0 < y less than or equal to 0.25) and Fe3-xCoxO4 (0.84 less than or equal to x less than or equal to 1.38). The 1100 degreesC isotherm of the pseudoternary system La2O3-CoO-Fe2O3 in air is constructed.
