X-ray diffraction patterns of SrFe1-xCoxO3-δ (x = 0, 0.2, 0.4, 0.6, 0.8)

The dataset consists of three raw X-ray diffraction (XRD) files collected using a Phillips X’Pert Pro diffractometer (CuKα radiation (𝜆 = 1.541 Å), under 40 kV and 30 mA). The diffraction patterns of SrFe1-xCoxO3-δ (x = 0, 0.2, 0.4, 0.6, 0.8) were collected at room temperature. Collected XRD data enabled the evaluation of the phase composition of samples and the crystal structure of synthesized materials. The XRD patterns were later analyzed using HighScore Plus XRD Analysis Software.
The samples were synthesized using the solid-state reaction method. Stoichiometric amounts of SrCO3, Fe2O3, and Co3O4 were ball-milled and calcined at 950 ℃ for 24 h. The resulting powder was then milled again, uniaxially pressed (100 MPa), and sintered for 24 h at 1200 ℃ for all samples aside from the SrFe0.2Co0.83-δ, which was sintered at 1050 ℃. NiO was used for the densification in the second step of the synthesis for all samples.
