Description
Three sodium aluminophosphate glasses proposed for the immobilization of high- and medium-level radioactive wastes were studied by IR and ESR spectroscopy. This study involves the effect of Cs2O, SrO, CoO, CaO, Fe2O3, SO3, and NaCl on the anionic motic of the glasses. It is shown that the structural network of sodium aluminophosphate glasses consists of interlinked [PO4] and [AlO4] groups. The addition of Cs2O (instead of Na2O) and Fe2O3 (instead of Al2O3) does not cause any appreciable changes in glass structure. The addition of SrO, CoO, CaO, SO3, NaCl, and simulated high-level radioactive waste oxides somewhat reduces the degree of polymerization of the structural network
