Y211 was added to the Y257 superconducting material at concentrations of 0, 0.10, and 0.20 mol using a solid-state reaction synthesis method. As the concentration of Y211 increased, both the onset critical temperature and the offset critical temperature decreased. The synthesized samples contained a combination of superconducting and non-superconducting compounds. The superconducting compound exhibited an orthorhombic structure with the Pmmm space group. Additionally, three different types of non-superconducting compounds were identified in the samples. The percentage of non-superconducting compounds increased with the addition of Y211. The surface morphology revealed heterogeneous elements and a random distribution of grain sizes. The samples contained Y, Ba, Cu, and O elements without any detectable impurities.
