Abstract:

Since the BSCCO 2212 superconducting system has an openstructure due to the addition and partial replacement methods, many studies have been carried out and the articles have been published. In this study, the effect of Ga on the superconductivity of the structure was investigated by measuring the susceptibility on the samples obtained by increasing the Ga ratio by performing Bi-Ga partial replacement at a certain ratio in the BSCCO 2212 superconductor. Vickers microhardness measurements were used to examine the mechanical properties of each sample. x-ray diffraction (XRD) analysis results were evaluated in order to determine the structural properties of the samples and crystal structure formations were observed by scanning electronmicroscope (SEM) images
