Liquid-line corrosion of nickel in molten sodium carbonate at 1000/sup 0/C under reduced air pressure was measured as a function of time and of air pressure. The observed attack profile approached a circular arc whose depth increased parabolically with time. Attack depth increased with air pressure from zero under an inert environment passed through a maximum, and decayed approximately hyperbolically at higher (subatmospheric) pressures. These observations are shown to be quantitatively consistent with rate control by the electron-transfer step of the cathodic process, reduction of peroxide.
