摘要
In this study, the role of gamma irradiation on lanthanum-added Bi1.85Pb0.35Sr2Ca2LaxCu3Oδ (BSCCO) bulk ceramic superconductors prepared by conventional solid state sintering method was examined. For this purpose, microstructure, critical current densities (Jc), and condensation properties of samples were characterized in detail before and after the application of gamma irradiation. These characteristics were analyzed by Scanning Electron Microscopy (SEM), Magnetic Hysteresis (M-H) curves, and density measurements, respectively. It was observed from SEM images that many samples had a layered and porous grain structure, characteristic of high temperature superconductors. It was found that the critical current densities calculated from the width of the M-H curves do not behave proportionally to the increasing gamma radiation intensity. It was found that the density values of the samples determined by Archimedes method were in the range of approximately 71–84% of the theoretical value.
