Effect of Pre-treatment on the Microstructure and Superconducting Properties of Bi-2223/Ag Tapes

摘要：

　　The effect of pre-treatment on the microstructure and critical current of (Bi,Pb)-2223/Ag tapes has been investigated.Experimental results show that pre-treatment has important influences on the formation and the grain size of the (Bi,Pb)-2223 phase as well as the performances of Bi-2223/Ag tapes.During the pre-treatment process,the decomposition of the 3321 phase enhances the growth of (Bi,Pb)-2212 grains,which promotes the formation of (Bi,Pb)-2223 phase because it followed the size and orientation of the original (Bi,Pb)-2212 phase.As a result,the properties of Bi-2223/Ag tapes were remarkably improved.
