METHOD TO PRODUCE HIGH-TEMPERATURE SUPERCONDUCTING MATERIAL BiSrCaCuO+δ Russian patent published in 1996 - IPC

Abstract SU 1812761 A1

FIELD: high-temperature superconducting materials synthesis. SUBSTANCE: charge of stoichiometric composition corresponding to composition of material Bi2Sr2CaCu2O8+δ is prepared and annealed, melted and hardened in the open air and then it is subjected to thermal treatment under temperature of 840 - 845 C at least for 10 hours. After that material has share of BI-2212 phase equal to 70 - 90 %. EFFECT: simplified process.
