Notes:
The effect of pre-treatment on the microstructure and critical current of (Bi,Pb)-2223/Ag tapeshas been investigated. Experimental results show that pre-treatment has important influences on theformation 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 sizeand orientation of the original (Bi,Pb)-2212 phase. As a result, the properties of Bi-2223/Ag tapes wereremarkably improved
