The partial Substitution for (Bi) instead of (Pb) and studying the Effect on the Electrical Properties of the Superconducting System (BBCCO)

Abstract

In the current study, we investigate the effect of (Pb) substitution instead of (Bi) on the properties of the superconductor compound (Bi2-xPbxBa2Can-1CunO10+δ) with (x=0,0.05,0.1,0.15,0.2). The samples were prepared by solid state reaction method(SSR). X-ray diffraction technique (XRD) was used to estimate the structural properties of the specimens which show an orthorhombic crystalline structure for all the specimens. X-ray diffraction analysis of the pure and substituted analysis showed that all samples contain a high percentage of high phase (Bi-2223) in addition to some other phases with a few impurities at the end of the chart and an increase in the intensity of the high phase peaks (Bi-2223) .
