METHOD FOR PRODUCTION OF A HIGH-TEMPERATURE SUPERCONDUCTOR IN SYSTEM SODIUM - SODIUM TELLURIDE

摘要

FIELD: high-temperature superconductor production. ^ SUBSTANCE: invention refers to the technology of high-temperature superconductors production in metal-metal oxide system and can be used for production of compounds with special physical properties. Tellurium powder and metallic sodium is heated in reactor under vacuum 5x10-4 torr to the temperature 200C, aged for 1 hour and cooled down to room temperature. ^ EFFECT: production of superconductor with the temperature of transition into superconductive state 35 K with simultaneous increase of reproducibility of synthesis results. ^ 1 dwg, 1 dwg, 1 ex
