METHOD FOR MANUFACTURING SUPERCONDUCTIVE MATERIAL BASED ON Bi-2223 WITH CRITICAL TRANSITION TEMPERATURE OF 197 K Russian patent published in 2015 - IPC C04B35/45 H01B12/00

Abstract RU 2568463 C1

FIELD: electricity.

SUBSTANCE: invention is referred to manufacturing of new high-temperature superconductive (HTSC) and it allows manufacturing the material featuring superconductivity at temperature of 197 K. This invention can be used widely in power engineering as energy-saving material, in particular it is the most appropriate base for HTSC cables. Upon cooling below temperature of superconductive transition (T_s) a sample of standard composition of Bi-2223 is placed into vacuum (P≤10^-6 Torr), and at impact of ambient pressure of P≤10^-6 Torr this sample of material Bi-2223 demonstrates properties of superconductive material with transition temperature of 197 K.

EFFECT: superconductive material manufactured by the above method has higher critical temperature than all known high-temperature superconductive materials.
