Abstract

See full text

An electrode for electrolytic fluorination contains nickel as a base material with a fluorine content <1,000 ppm. Preferably, in at least a surface portion thereof, the nickel content ≥99 mass %, the iron content ≤400 ppm, the copper content ≤250 ppm, and the manganese content ≤1,000 ppm. A method for producing an electrode includes arranging a nickel base material electrode in a nickel plating bath as a cathode, and applying nickel plating to the nickel base material electrode by electrolytic nickel plating, the method including (1) using, as an anode, a nickel component deposited on a cathode, or a nickel component that has settled in a molten salt, in a process of producing nitrogen trifluoride by molten salt electrolysis using a nickel base material anode, or the nickel base material anode; or (2) using, as the cathode, the nickel base material anode.
