摘要

Critical temperatures(T_c) and critical currents (I_c) of Pb-Bo-Sr-Ca-Cu-O (PbBiSCCO) superconductors containing 10, 25 or 30 wt./100 Ag or AgCu or AgIn are reported. Specimens of 24-h annealed, 10 wt./100 added metal/alloy composites show the highest critical currents, which is much higher than pure PbBiSCCO. Samples annealed for 24 h bestow better transport property than the 48-h annealed samples for the same composition. The connectivity effect of metal/alloy between superconducting grains can explain this finding. The I_c of AgIn composites is superior to AgCu but inferior to Ag composites. This finding is explained in terms of supercurrent transport properties.
