Studying the effect of partial replacement of the Sb nanocomposite on the structural properties of the superconducting Bi2-xSbxBa2Ca2Cu3O10+δ compound

The current work includes studying the effect of partial substitution of antimony nanoparticles instead of bismuth on the electrical and structural properties of the superconducting compound Bi2-xSbxBa2Ca2Cu3O10+δ, where x = 0, 0.1, 0.2, 0.3, and the samples were prepared by the solid state reaction (SSR) method. The samples were sintered in normal air and at a temperature of 800°C for 48 hours at a heating rate of 10°C/min. X-ray diffraction tests were carried out on the four samples of different antimony concentrations. The results showed that all samples had a orthotropic structure, with differences in the lattice constants (a, b and c, )with a clear increase in the dimension c = 36.6899 A° for the second sample when x = 0.1, as well as an increase in the percentage of the high phase HTP%, which equals 68.16%, and the formation of And the structure (morphology) by the SEM device for the samples, the formation of a granular size with Nano-dimensions was observed, and the element analysis for each sample was examined through EDS examination, as the results showed the presence of the elements and their different proportions in each sample.
