METHOD FOR PRODUCTION OF A HIGH-TEMPERATURE SUPERCONDUCTOR IN SYSTEM SODIUM-SODIUM OXIDE Russian patent published in 2012 - IPC C22C24/00 H01B12/00 

FIELD: high-temperature superconductors 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 surface of metallic sodium sample is oxidized in the reactor in the flow of dried oxygen with flow speed 5-10 ml/min at the room temperature for 25 minutes. The resulting sodium sample with the surface sodium oxide is cured at the temperature 200°C in vial under vacuum 5x10^-4 torr for 4 hours and cooled down to room temperature.

EFFECT: provides for production of superconductor in sodium-sodium oxide system with the temperature of transition into superconductive state 45 K with simultaneous increase of reproducibility of synthesis results.
