Corrosion of Iron by Li2 CO 3 Melt at 1073 K

Abstract

The corrosion of iron has been studied gravimetrically in the presence of melt in atmosphere at 1073 K in order to examine the effect of the amount of the melt on the metal on the corrosion process. When the surface of Fe was covered with a thin film of melt, the total weight of the specimen increased, the corrosion reaction followed a linear rate law, and the major product was iron oxide. At that time the weight gain was proportional to the metal loss. When the metal was fully immersed in the melt the weight of the cell decreased. The corrosion reaction of Fe was relatively slow in this case and the major product was while a small amount of could also be formed.
