Mahtali, S. Chamekh] Among the superconducting phases of bismuth-based Bi-Sr-Ca-Cu-O, compound Bi2Sr2Ca2Cu3O10+δ (Bi-2223) is the most interesting because of its relatively high critical temperature (T C=95-110K) and numerous applications. However, this phase is also known for its low stability and the difficulty of purifying parasites phases including the Bi-2212. To this end, the Pb used in relatively high proportions can stabilize, purify, and improve the further enhancement of T C. The influence of Pb on structural, superconducting and magnetic properties has been extensively investigated in polycrystalline Bi2−x PbxSr2Ca2Cu3O10+δ ceramics (0<x<1). For low Pb amounts, structural analysis shows that the Bi-2223 phase is difficult to achieve without the Bi-2212 phase, and for high Pb content a large fraction of secondary phases containing Pb is detected. Our results confirm that the optimal Pb content for obtaining a Bi-2223 single phase is x=0.3,0.4.
