METHOD TO PRODUCE HIGH-TEMPERATURE SUPERCONDUCTING MATERIAL Bi₂Sr₂CaCu₂O₈+amp;delta;

摘要

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.
