Nitrogen evolution as anodic reaction in molten LiF-CaF2

Abstract

The electrochemical behaviour of nitride ions has been studied in fluoride melts (eutectic LiF-CaF2) by cyclic voltammetry and square wave voltammetry. The purpose of this work is to propose an alternative way for anodic reaction in molten fluorides processes. Thermodynamical analysis can be used for the evaluation of the anodic material regarding to its oxidation potential and reactivity with nitrogen. Then electrochemical investigations confirm the oxidation of nitride ions into nitrogen in a one-step process exchanging 3 electrons, and let propose several materials usable for nitrogen evolving.
