A Reaction Rate Study in Hydrofluoric Acid of the Dissolution of Titanium and the Alpha Solid Solution of Oxygen in Titanium
Abstract
Studies were conducted into the mechanism of dissolution in hydrofluoric-hydrochloric acid mixtures of titanium and of alpha solid solution specimens of oxygen in titanium. Special precautions were taken to preserve the trivalent state of titanium. For titanium a rate order of 0.76 and an activation energy of 6.9 ± 0.5 kcal was found and for titanium in TiO x a rate order of 0.83 and an activation energy of 6.6 ± 0.5 kcal. Furthermore, the oxygen content of TiO x, within the range studied, had no effect on the rate of hydrogen evolution; all specimens evolved hydrogen at the same fixed rate per unit area for a given temperature. It is concluded that a diffusionally controlled reaction can best explain the results. © 1961.
