Current mathematical models of the glass corrosion process usually postulate that leach rates are determined by a simple interdiffusion process. Alkali ions of the glass are assumed to exchange with a hydrogen bearing species of the aqueous solution. However, until now no mathematical analysis was able to predict the development of concentration profiles in the surface layer for a number of different glass compositions and different experimental conditions. We believe that this lack is due to the inadequacy of the models to represent the actual processes taking place during aqueous corrosion. Some fundamental characteristics in the leaching process have never been adequately addressed in the current diffusion formulations for glass leaching. In particular, concomitant reactions such as phase separation1, internal hydrolysis2, condensation of silanol groups3, and exchange of network oxygen4 have often been neglected. Nevertheless, these reactions have been experimentally confirmed, especially for long-time corrosion. In the early stages, the reactions which accompany the ion exchange process may be different. In this paper, we investigate short-time leaching of a soda-lime glass in H2O and D2O.
