Title: IR and ESR spectroscopic study on the structure of aluminophosphate glasses simulating vitrified radioactive wastes

Abstract

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 Cs{sub 2}O, SrO, CoO, CaO, Fe{sub 2}O{sub 3}, SO{sub 3}, and NaCl on the anionic motic of the glasses. It is shown that the structural network of sodium aluminophosphate glasses consists of interlinked [PO{sub 4}] and [AlO{sub 4}] groups. The addition of Cs{sub 2}O (instead of Na{sub 2}O) and Fe{sub 2}O{sub 3} (instead of Al{sub 2}O{sub 3}) does not cause any appreciable changes in glass structure. The addition of SrO, CoO, CaO, SO{sub 3}, NaCl, and simulated high-level radioactive waste oxides somewhat reduces the degree of polymerization of the structural network.
