摘要：
The fabrication of Bi(Pb)-2223 multifilamentary wires by means of the powder-in-tube method and their electric and magnetic characterization are reported. High dentification and texturing degree of the ceramic and therefore high current capability of the silver-sheathed composites (J(c) almost-equal-to 10(4) A cm-2 at 77 K, 0 T) were obtained by repeated sintering and deformation processes. Multifilamentary cables with different geometrical arrangements of the superconducting filaments inside the silver matrix were also prepared and characterized. The microstructure of Bi(Pb)-2223 filaments was analysed by SEM and Auger electron spectroscopy (AES) and correlated to the electrical properties.
