Reformation of (Bi, Pb)-2223 Superconducting Phase after Complete Peritectic Melting (original) (raw)

Journal of Physics: Conference Series, 2006

Abstract

ABSTRACT Considerable fractions of (Bi, Pb)-2223 were recovered after the complete peritectic melting of that phase. The minimization of Pb-losses was a key-feature, so that only about 1.57 wt % of total Pb content was lost over the whole process. Therefore the system remained within the 2223 single-phase region. The new route employed here, including the participation of a stable liquid, should overcome some microstructural problems nowadays present in sintered 2223/Ag tapes, such as voids, cracks and bad grain connectivity. Further optimization of the complete melting-reformation process may reduce the fraction of secondary superconducting phases, which can act as weak-links.
