Аннотация
A model of oxygen ion transport in molten V2O5 is proposed. Within the framework of this model, the values of the parabolic rate constant of the catastrophic oxidation of copper in contact with V2O5 and oxygen flux through an ion transport membrane with liquid-channel grain-boundary structure on the basis of V2O5 are calculated as k′′ = 2.4 × 10–5 kg2/(m4 s) and J = 2.7 × 10–4 mol/(m2 s) at 700°C. These values are in agreement with the experimental data in order of magnitude, indicating the agreement between theory and experiment.
