Abstract:
The phase equilibria in the Sr-Fe-Ni-O system at 1100°C in air have been studied by x-ray diffraction, and the corresponding phase diagram at constant temperature and pressure has been constructed. The system has been shown to contain two solid-solution series at 1100°C in air: SrFe 1 - x Ni x O 3 - δ (0 < x 0.075, sp. gr. Cmmm) and Sr 3(Fe 1 - y Ni y ) 2O 7 - δ (0 < y 0.15, sp. gr. I4/mmm). Neither Sr 4(Fe 1 - z Ni z ) 6O 13 nor Sr(Fe 1 - z Ni z ) 12O 19 solid solutions have been identified. The lattice constants and structural parameters of single-phase samples have been refined by the full profile Rietveld analysis method. © 2009 Pleiades Publishing, Ltd.
