Properties of high-temperature superconductors (HTS) and synthesis technology

Abstract

The main results for the synthesis and study of superconducting high-temperature materials based on cuprates obtained by high-temperature synthesis are presented. The influence of the ratio of the primary components, time and exposure temperature on the output of the superconducting phase (Y123) in the composition was studied. It was found that the initial ratio of components, annealing temperature and aging time have a direct impact on the qualitative and quantitative formation of the conductive phase. The chemical, phase composition and morphology of the obtained samples were carefully studied. Optimal result (maximum conductive phase in Y-Ba-Cu-O system (Y123) size) at a temperature of 920°С with a retention time of 6 hours.
