Popis:	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 (TC=95–110 K) 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 TC. The influence of Pb on structural, superconducting and magnetic properties has been extensively investigated in polycrystalline Bi2−xPbxSr2Ca2Cu3O10+δ ceramics (0
