Post-mortem characterizations of G0.40Nd4C glass after alteration in alkaline environments. a X-ray diffractogram showing the precipitation of Na-P1 (ICDD 71–0962) and/or Na-P2 (ICDD 80–0700) zeolites. Scanning electron micrographs after leaching at an initial pH of 11.5 left to vary freely, b a cross section (back-scattered electrons) and c under secondary electrons observation: (1) zeolites, (2) altered glass, (3) epoxy coating resin. The scale bars represent 50 µm; other enlargements are presented in Supplementary Figure 2
