摘要：
The phase relations in the composition region SrFeO3 – δ–Fe2O3–BiFeO3 are studied in air by x-ray diffraction and electron microscopy. The 1000°C phase compatibility diagram is constructed. Sr1 – xBixFeO3 – δ solid solutions are prepared in the range 0 < x ≤ 0.8. Their lattice parameter is found to vary nonlinearly with x. Two new phases were identified: (Sr,Bi)3Fe4Oy (tetragonal lattice, a= 3.907(2) Å, c= 27.30(2) Å) and Sr0.6Bi0.4FeO3 – δ (tetragonal lattice,a = 5.555(2) Å, c= 11.848(5) Å).
