ANALYSIS OF THE CRITICAL TEMPERATURE OF SUPERCONDUCTOR SAMPLES BASED ON Bi1,7Pb0,3Sr2Ca(n-1)Cu(n)Oy (n=9-20) PRECURSORS OBTAINED IN A LARGE SOLAR FURNACE

Abstract

In modern science and technology, the efficient use of renewable energy sources represents one of the priority directions. Among them, solar energy stands out as a clean, inexhaustible, and environmentally safe source. By concentrating high fluxes of solar radiation, Large solar furnace (LSF) make it possible to achieve extremely high temperatures, which provide advantages over conventional heating technologies in terms of both efficiency and environmental sustainability. In the field of materials science, the use of solar energy is emerging as a particularly promising approach for the synthesis of high-temperature superconductors. The synthesis of ceramic samples of the Bi–Pb–Sr–Ca–Cu–O system in LSFs not only ensures energy efficiency but also enables the formation of new features in the phase structure and morphology of the material. Therefore, determining and analyzing the critical temperature of layered superconducting samples of composition Bi1,7Pb0,3Sr2Ca(n-1)Cu(n)Oy (n=9-20), synthesized using concentrated solar energy, is of significant scientific importance [1].
