The model developed to represent interactions between oxygen (at low pressure) and high-temperature transition metals enabled experimental results obtained under steady-state conditions to be verified for platinum, rhenium, tungsten, molybdenum, tantalum, and niobium. This model assumes that the adsorption of oxygen is the only reaction that can occur between the gas phase and the surface. The results obtained for Ta and Nb undergoing isothermal desorption are presented. These two metals dissolve oxygen and, as a result, two regimes occur when the temperature and pressure vary. These steady-state and transient regime results are in agreement with the model envisaged and also with available thermodynamic data. (FR)
