Abstract
The electrochemical behavior of nitride ions in an LiCl‐KCl eutectic melt has been studied by cyclic voltammetry, chronopotentiometry, chronoamperometry, and gas analysis. Nitride ions are oxidized to form nitrogen gas almost quantitatively on nickel electrodes according to the following reaction
This is a reversible, one‐step, three‐electron reaction governed by a simple diffusion‐controlled charge‐transfer process. The diffusion coefficient of nitride ion was found to be 
at 470°C.
