Detailed characterization was carried out on an iron phosphate glass waste form containing 20 wt.% of Ce-rich complex nuclear waste mixture.
/Fe ratio of this waste loaded iron phosphate glass was investigated using Mössbauer spectroscopy, which reveals the presence of iron cations
in two different oxidation states (Fe2+
) and all Fe2+
occupied the octahedral coordination state, while some Fe3+
occupied the tetrahedral
coordination state and the rest occupied the octahedral coordination state. With the addition of Fe2
to the glass, the P—O—P bonds are replaced by
bonds, which are more chemically durable. The measured properties of the waste loaded glass comply with the characteristics
of both pure iron phosphate glass and literature
