The Effect of Sintering Time on the Stabilization of the Bi-Pb-Sr-Ca-Cu-O Superconducting Phase

ABSTRACT

A high-Tc superconducting phase was obtained using long sintering time of 210 hours. From XRD and SEM analyses, it could be confirmed that the particles were plate phase, of which the structure is tetragonal system with lattice parameter a=b=5.44${AA}$, C=37.18${AA}$. Resistance and current density measurements were carried out using 4 probe method. The experimental data revealed that the stable high-Tc superconducting phase was easily formed by addition of Pb to Bi-system. Therefore, we could find the sintering condition to synthesis the system having the largest fraction of high Tc phase.
