The development of nuclear technology leads to the generation of radionuclide contaminated soils, which require efficient and rapid disposal methods. In this study, with microwave sintering method, the simulated radionuclides contaminated soils were successfully immobilized as glass-ceramics at 1200 °C with 30 min. The temperature effect, phase evolution, morphology, element distribution of simulated radioactive contaminated soil were investigated. The XRD results showed that Nd 3+ were immobilized into glass-ceramic phases with Nd 2 O 3 content increased up to 25 wt %. In addition, molecular dynamics simulation (MD) results showed the simulated radioactive contaminated soils were composed of [SiO 4 ] tetrahedron, and Si-O-Si bonds had an important effects on the glass structure forming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
