Abstract
Diffusion processes play a dominant part in the macro kinetics of Fe, Ni and Co
oxidation by calcium and sodium sulfates. Here, the reaction product forms a compact covering
which spatially divides the reagents on the surface in the same way as in the oxidation and
sulfidization of metals by oxygen and sulfur. Therefore, it is possible to assume in advance that
interaction of metals with calcium and sodium sulfates will be determined not by the actual
chemical reaction properly but by the diffusion transport processes.
