Potential/pO\*-diagrams have been developed for the iron/molten-sodium-nitrate system at 600 and 700°K. Four well-defined regions corresponding respectively to metal corrosion, immunity, passivity and passivity breakdown are shown in the diagrams. R&urn&On a d&eloppB les diagrammes potentiel/pOa-pou

✦ Synopsis
The reversible decomposition voltage of sodium nitrate was measured after electrolysis current was switched off in a cell containing the molten salt and platinum electrodes. The residual reversible cell is represented by the following scheme: Na(l)/NaNO,(l)/NO,,O,,Pt.
(I) The theoretical standard emf calculated from thermodynamic data for the reaction

In the electrolysis of pure molten silver nitrate with a silver cathode and a platinum anode at temperatures from 220 to 380°C a reversible cell is formed. When the system is electrolysed for a short time at a steady current density and then the current is interrupted, it tends to reach after a few
