摘要	The phase assemblage and particle sizes of precursor powders have been optimized in a sequence for fabricating Ag/BSCCO-2223 composite tapes. Firstly, an optimal calcination temperature was determined based on the experimental results. Then, the precursors calcined at the optimal temperature were ball-milled for different dwell times to obtain varied particle sizes. The effects of both the phase assemblages and particle sizes of the precursor powder on the phase formation, microstructure and transport J(c) of Bi-2223/Ag tapes have been investigated. The results show that the precursor phase assemblage has a large impact on the reaction routes, microstructure, and Jc property. Meanwhile, a fine powder is beneficial for the grain growth, alignment, and Jc enhancement in fully reacted tapes. The best J(c) was achieved in the tape made from the powder after optimizing the phase assemblage and particle size.
