초록

Bi-system high-$T_c$ superconductors with the nominal composition $(Bi_{0.7}Pb_{0.3})_2-Sr_{2}Ca_{2}Cu_{3}O_{x}$ have been prepared by PJL method. The critical temperature (offset temperature) of the sample annealed for 13 hours in air was 102K. And the results of X-ray diffraction(XRD) patterns, scanning electron microscope (SEM) images and energy dispersive X-ray (EDX) spectra analyses, it was found that PJL method is so effective to reduce the heat treatment period.
