The aim of this work was to contribute to the dissolution behavior by dissolving waste glass in high alkaline solution. To understand the dissolution behavior, the effect of temperature, particle size distribution, stirring and the nature of the alkaline solution were performed as a function of time. The experiments based on gravimetric, elementary and differential thermal analysis, and SEM measurements showed that all considered parameters displayed the same feature and could be due to a fast ion exchange and a diffusion mechanism associated with the back precipitation of silica species. The alkali cation size played also a role on the dissolution mechanism.
