Phase Equilibria of the High Tc Superconductors in the (Bi, Pb) -SR-Ca-Cu-O System



Winnie Wong-Ng, Lawrence P. Cook, W Greenwood, Anthony J. Kearsley


Applications of (Bi,Pb)-Sr-Ca-Cu-O phase equilibria include material synthesis, melt processing and single crystal growth. Both liquidus and subsolidus data are of central importance. For the determination of liquidus data, we have used a wicking technique to capture the melt and perform quantitative microchemical analysis. Melt compositions have been obtained for multicomponent volumes which allow for the construction of the crystallization fields for high Tc phases in the title system. Subsolidus multi-phase equilibria of the Pb-free 2212 (Bi:Sr:Ca:Cu), and Pb-doped 2223 phases, and the approximate crystallization fields of these phases are described.
