초록

GdBa$_2$Cu$_3$Ox superconductors were prepared by ceramic powder compacting method. X-ray powder diffraction patterns and SEM microphotographs were taken to analyze phase and microstructure, and electrical properties were investigated by 4-point probe method. The results show that the $N_2$atmosphere enhances the formation of high Tc(critical temperature) phase, but the Tc is independent of sintering conditions.
