METHOD FOR PRODUCTION OF A HIGH-TEMPERATURE SUPERCONDUCTOR IN SYSTEM IRON - IRON OXIDE Russian patent published in 2012 - IPC C01G49/00 H01B12/00 

FIELD: electrical engineering.

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 method involves partial reduction of fine powder of iron oxide Fe₂O₃ sized less than 50 μm to metal α-Fe while maintaining iron oxide FeO in each powder volume in the flow of dried hydrogen with the speed 100 ml/min at the temperature 350°C for 5 minutes and cooling at the room temperature.

EFFECT: production of superconductor in iron-iron oxide system with high temperature of transition into superconductive state with simultaneously increased reproducibility of synthesis results.
