摘要: The phase equilibria in the Sr-Fe-Ni-O system at 1100°C air have been studied by x-ray diffraction, and corresponding diagram constant temperature pressure has constructed. shown to contain two solid-solution series air: SrFe1 − x Ni O3 δ (0 < x ≤ 0.075, sp. gr. Cmmm) Sr3(Fe1 y )2O7 y 0.15, I4/mmm). Neither Sr4(Fe1 z )6O13 nor Sr(Fe1 )12O19 solid solutions identified. lattice constants structural parameters of single-phase samples refined full profile Rietveld analysis method.
