An alternative two-powder process for the synthesis of superconducting (Bi,Pb)-2223/Ag clad wires by the powder-in-thetube (OPIT) process is described. The first powder, of nominal stoichiometry Bil.sPbo.4Sr2CaCu2Os, is a mixture of (Bi,Pb)-2212 and Ca2PbO4. The second powder, of nominal stoichiomet
Ag-sheathed (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O 10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a-b planes of the superconductor. The fabrication process we propose allows
