Study of the heterogenous reaction between iron lead oxides

Different theories are proposed in the literature to explain passivation mechanisms of iron by means of the use of lead compounds. In some cases the protective action is related to the formation of lead soaps with vegetable oils or oleoresinous binders. These soaps are partially dissolved from the f...
