METHOD FOR PRODUCTION OF A HIGH-TEMPERATURE SUPERCONDUCTOR IN SYSTEM COPPER - COPPER OXIDE Russian patent published in 2012 - IPC C22C29/12 H01B12/00 

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. The copper powder is oxidized in the reactor in the flow of dried oxygen with flow speed 20-30 ml/min with heating of the powder from the side of oxygen supply to the temperature 700°C for 3 minutes. The resulting sodium sample with the surface sodium oxide is cured at the temperature 1,000°C in vial under vacuum 5x10^-4 torr for 1 minute and cooled down to room temperature.

EFFECT: production of superconductor with the temperature of transition into superconductive state 90 K with simultaneous increase of reproducibility of synthesis results.
