Wet chemical method was applied with the intention of obtaining Lu_1-xSr_xFe_0.5Cr_0.5O₃ (0 ≤ x ≤ 1) perovskites in polycrystalline form. A systematic study of the crystal structure of the main perovskite phase obtained as well as a characterization of impurities was performed by X-ray techniques: powder diffraction (PXRD), high resolution emission spectroscopy (HR-XES), and photoelectron spectrometry (XPS). The PXRD data of Lu_1-xSr_xFe_0.5Cr_0.5O₃ (0 ≤ x ≤ 1) were refined using Pbnm orthorhombic unit cell for the perovskite structure. Only samples with x = 0 and x = 0.1 resulted pure; as the amount of Sr increases, it is segregated as impurities, first as SrCrO₄ and then as SrFe₁₂O₁₉. The mean oxidation state of Cr in the analyzed samples was obtained from HR-XES by quantifying spectral changes in the Cr-Kβ" and Cr-Kβ_2,5 regions by different methodologies: statistical parameters and multivariate methods. The results were compared with the ones obtained by PXRD and XPS. With the last technique Cr⁶⁺ ionic concentrations were obtained through the spectral analysis in the region Cr2p_3/2–580eV. Similar Cr⁶⁺ ionic compositions were obtained using the three X-ray techniques.

应用湿化学方法的目的是获得多晶形式的Lu _1-x Sr _x Fe _0.5 Cr _0.5 O ₃ (0 ≤ x ≤ 1) 钙钛矿。通过 X 射线技术对获得的主要钙钛矿相的晶体结构和杂质进行了系统研究：粉末衍射 (PXRD)、高分辨率发射光谱 (HR-XES) 和光电子能谱 (XPS) . Lu _1-x Sr _x Fe _0.5 Cr _0.5 O ₃的PXRD数据(0 ≤ x ≤ 1) 使用 Pbnm 正交晶胞对钙钛矿结构进行细化。只有 x = 0 和 x = 0.1 的样品才是纯的；随着Sr量的增加，它作为杂质分离，首先分离为SrCrO ₄，然后分离为SrFe ₁₂ O ₁₉。分析样品中 Cr 的平均氧化态是通过 HR-XES通过不同方法（统计参数和多变量方法）量化 Cr-Kβ" 和 Cr-Kβ _2,5区域的光谱变化而获得的。结果与通过 PXRD 和 XPS 获得的。使用最后一种技术，通过光谱分析在 Cr2p _3/2 –580eV区域获得Cr ⁶⁺离子浓度。类似的 Cr ⁶⁺ 离子组合物是使用三种 X 射线技术获得的。
