Abstract
The present invention provides an electrolytic synthesis method of nitrogen trifluoride, comprising electrolytically synthesizing nitrogen trifluoride gas from ammonium fluoride in an ammonium fluoride-containing molten salt mixture using a carbonaceous electrode as an anode, wherein the method comprises: a step of dissolving, in the molten salt mixture, metal ions capable of electrolytically yielding a highly oxidized metal fluoride through reaction with fluorine radicals (F.) that are generated upon the discharge of fluoride ions which are a component of the ammonium fluoride, thereby reacting the metal ions with the fluorine radicals (F.) to yield the highly oxidized metal fluoride, and reacting the highly oxidized metal fluoride with ammonium ions on a surface of the electrode and in a solution to synthesize nitrogen trifluoride gas.
