Abstract
Melting information for the Pb-doped 2223 high Tc phase in the Bi(Pb)-Sr-Ca-Cu-O system is important for the superconducting wire and tape industry. This paper examines the melting equilibria of a composition Bi1.8Pb0.4Sr2Ca2.2Cu3Ox under oxygen. The subsolidus multiphase volume consists of 2223, (Ca,Sr)2PbO4 (1x20), 2212, (Sr,Ca)14Cu24O41 (014x24), and (Ca,Sr)d2CuO3 (0x21). This multiphase volume is also one member of the 29 five-phase volume set prepared under 7.5% O2 that contains 2223. A procedure which involves the combined use of DTA/TGA, He/Liquid N2 Quenching methods, powder x-ray diffraction, SEM/EDS, and a wicking technique to capture the melt for performing quantitiative microchemical analysis were employed for this investigation.Citation
