On the anodic passivity of iron in molten potassium bisulphate
The electrochemical behaviour of pure iron anodes in molten KHSO<sub>4</sub> at 250°C was studied. Typical passivity phenomena were observed under potentiostatic as well as galvanostatic runs. A transition time related to the onset of full passivity was determined. The passive film was s...

description |
The electrochemical behaviour of pure iron anodes in molten KHSO<sub>4</sub> at 250°C was studied. Typical passivity phenomena were observed under potentiostatic as well as galvanostatic runs. A transition time related to the onset of full passivity was determined. The passive film was studied by X-ray diffraction. Its average structure corresponded to Fe<sub>3</sub>O<sub>4</sub>. The mechanisms of passivation and corrosion of passive iron are discussed on the basis of behaviour of passive iron in aqueous systems. |
