High-Temperature Superconductors of the Bi1.7Pb0.3Sr2Ca(n– 1)CunOy (n = 2–20) Series Synthesized under the Influence of Concentrated Solar Energy

The advantages of the melt technique for the synthesis of superconducting materials are shown in comparison with the solid phase technique. Glass crystal precursors of the Bi1.7Pb0.3Sr2Ca(n – 1)CunOy series (n = 2–20) synthesized with SFAQ-T (Super Fast Alloys Quenching) technology under the influence of concentrated solar energy are used to produce superconducting Bi/Pb phases with increased superconducting transition temperatures.
