Rutile bears some unique features in regard to oxygen transfer with the outer atmosphere, at high temperatures. It possesses very high chemical diffusivity. This diffusivity becomes apparent while performing reequilibration experiments in a final atmosphere of pure oxygen. Conversely, the oxidizing-reducing reaction with CO/CO2 mixtures at the rutile surface is always a slow process.
