| 英文摘要 | 4 kinds of BSCCO 2223 precursor powders with different Ca contents were prepared by spray drying method. The influence of Ca doping on the phase evolution, microstructure and transport property of Bi-2223/Ag tapes was studied. It is found that increasing the Ca content in initial stoichiometry can accelerate the 2223 phase formation and improve the transport I-c, however, much more Ca-rich non-superconducting secondary phases were also induced at the same time. It is supposed that Ca doping has increased the amount of liquid phase during the heat treatment, which in turn improved the phase formation, grain growth and grain connectivity, hence resulting in the enhanced current transport ability. |
