Characterisation of heterogeneous molybdate and chromate phase assemblages in model nuclear waste glasses by multinuclear magnetic resonance spectroscopy

“…17 Indeed, there exists a series of cesium chromates with identical stoichiometry and similar structure to cesium molybdates (Cs 2 XO 4 , Cs 2 X 3 O 10 , and Cs 2 X 4 O 13 , where X = Mo or Cr). [18][19][20][21][22][23] Chromium is known to exist in waste glasses as eskolaite (Cr 2 O 3 ), or to partition into spinel-type compounds, 24 but the partitioning of Cr into molybdate phases has yet to be explored. We have prepared a series of chromium-containing sodium borosilicate model waste glasses (including cesium and molybdenum) to examine the fate of chromium upon devitrification, specifically its partitioning among glassy and crystalline phases.…”
