Superconducting properties of (Bi,Pb)₂Sr₂Ca₂Cu₃O_x (BSCCO-2223) superconductor ceramics prepared by conventional solid-state reaction and co-precipitation methods

Abstract The (Bi,Pb) 2 Sr Ca Cu 3 O x (BSCCO-2223) samples were prepared by conventional solid-state reaction and co-precipitation methods. crystal size, cell parameter, structure identified from X-ray diffraction (XRD). peaks drawn have higher intensities the width of narrower compared to sample method. Slight difference in value lattice parameters between also noticeable. Concentration defects increased distortion that cause changes these parameters. electrical properties superconductors investigated using cryogenic four-point probe AC susceptibility. method was able reach critical temperature, T C at 106 K other sample, 97 K. Meanwhile Scanning Electron Microscope (SEM) micrographs for showed more random grain alignment porous structures. microstructures growth results Bi-2223 reflected heat temperature applied during sintering process. In short, research work reveals produces better quality high superconductor with due homogeneity resulted chemical reactions.
