Experimental data for: Dissolution of simulated nuclear waste glass at high surface area to solution volume, high pH and 70 °C: comparison of International Simple Glass and SON68 glasshttps://doi.org/10.26165/JUELICH-DATA/HC3IOIBrandt, FelixCaes, SébastienKlinkenberg, MartinaBarthel, JuriLiu, SanhengLemmens, KarelBosbach, DirkFerrand, KarineJülich DATA2024-06-282024-10-01T09:47:01ZLong-term static dissolution experiments, lasting up to ~1500 days, were conducted on International Simple Glass (ISG) and SON68 glass under hyperalkaline pH, at 70 °C, and at a very high glass surface area to solution volume ratio. This dataset contains the experimental data of pH evolution with time, element release and normalized mass losses of several elements. Furthermore, additional microscopic data are provided.Earth and Environmental SciencesdoiKlinkenberg, Martina2024-06-11CC0CC0 Waiver
