Effect of Time of Heat Treatment on the Growth of Superconductive Phase of Bi-System Superconductor

Nobutaka Oguro; Minoru Otaguchi; Yoshinari Kaieda; Keiji Itoh

The effect of the heat treating time is investigated to develop the fabrication technique of Bi system superconductor. A temperature just below the softening of the specimen is selected as a sintering temperature. The content of Pb additive is substituted for 20% of Bi. Various heating time and the growth of the superconducting phase are investigated. The measurements of the magnetic susceptibility, X-ray diffraction and SEM observation of the superconducting phase are carried out. From the results of the experiments to investigate the effect of heat treating time, the specimen with 300 hours of heat treatment time has most high Tc phase.
