Simulated waste glasses which were 25 wt% Magnox glass, 36 wt% Magnox glass and International Simple Glass (ISG) were subjected to aqueous corrosion in static mode with deionised water at 90 °C for 7 to 28 days. Magnox glass is Mg- and Al- rich while ISG has only 6 components but no Mg in the composition. These glasses were assessed before and after corrosion using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) with Energy X-Ray...
