General and specific features of oxidation of crushed metals and their mixtures under conditions of considerable mechanical effects on surface of solid reagents

In the presence of intensive mixing and considerable mechanical effects on the surface of metal particles, the average oxidation rates of many metals are quite close to each other and practically independent on the nature of the metal. During the oxidation of mixtures of two metals, differences in the average rates of their oxidation under identical conditions occur and manifest themselves quite clearly. The differences in oxidation rates considerably depend on the nature of the metal and the ratio of the amounts of metals in the initial load. These differences are explained by preservation by metal particles of their oxidizer (in this case, molecular iodine) during their initial contact with the oxidant-containing medium of the bulk phase, which contributes to the stable preservation of the initial distribution throughout the entire further oxidation process.
