During the main thrust of the HCDA studies, it was found that sodium uranates, especially Na/sub 3/UO/sub 4/, were formed when the Na-U-O system was subjected to high temperatures approximating those of the HCDA. Mechanisms through which these rather complicated compounds are formed remain unknown. The purpose of these SIMS and ESCA studies was to detect the formation of any precursor ion species to the sodium uranates. The ESCA results agree with theory and support the presence of U/sub 2/O/sub 7/ /sup 2 -/ in Na/sub 2/U/sub 2/O/sub 7/; however, SIMS analyses show no evidence of possible uranate precursor formation in an Ar/sup +/ sputtered ion beam.
