A virtually pore-free oxide layer is formed during the heating of heavy metals in an oxidizing atmosphere. It was shown in earlier publications that the diffusion in this layer may be interpreted as a migration of ions and electrons. Formulas for the quantitative calculation of the speeds of oxidation were derived on the basis of these assumptions. It is to be the task of this work to investigate the oxidation speeds of metals in their dependence on oxygen pressure and then to compare them with the earlier predictions. Further, statements concerning the oxidation speeds of alloys are also to be examined.
