    摘要： An article and method of manufacture of a (Bi,Pb)--Sr--Ca--Cu--O superconductor comprisingcalcinating powders of superconductor precursors of PbO, Bi.sub.2 O.sub.3, SrCO.sub.3 or SrO, CaCO.sub.3 or CaO in air to obtain a 2223 superconductor lump and second phases;crushing the lump into powder;molding the powder into a superconductor body;disposing the body within silver powder to form a composite;molding the composite;heat treating the composite to increase the bond strength of the silver powder; andworking the composite into a useable shape by rolling and drawing while applying intermediate and final heat treatments to obtain a final product.
