摘要：

(Bi,Pb)-2223 superconducting ceramics prepared by heat treatment at 840°C and containing 0.1 to 0.5 wt % fine-particle NbC additions were characterized by microstructural analysis, x-ray diffraction, and magnetic susceptibility measurements. The introduction of 0.1 wt % NbC was found to raise the 77-K zero-field critical current density by a factor of 2 to 3, reduce the superconducting transition width, and slightly increase Tc .
