Potentiodynamic behaviour of graphite and platinum electrodes in molten sodium nitrate-potassium nitrate eutectic

The electrochemical behaviour of graphite and platinum electrodes has been studied in molten alkaline nitrates using cyclic voltammetry. The voltammograms obtained with graphite exhibit two current peaks not observed on platinum under similar conditions. An electrochemical reaction involving O<su...
