Post-mortem characterizations of G0.40Nd4C glass after alteration in COx water. a X-ray diffractogram showing the precipitation of neodymium hydroxycarbonate (ICDD 27–1296), cristobalite-related sodium magnesiosilicate63 (ICDD 47–1498), and calcium sulfate and carbonate (ICDD 33–0311, 47–1498, 33–0268). Sodium chloride (ICDD 05–0628) formed on the sample surface as it dried after removing it from the COx water. Backscattered electron scanning micrographs showing the crystallization of b phyllosilicates (1), RE carbonate (2), and c calcium sulfate. The scale bars represent 10 µm
