Abstract : Sodium, magnesium, and zinc insertion compounds formed by alpha-UO2. 9, U3O8, gamma-UO3, and delta-UO3 at room-temperature were prepared. The products were characterized by powder X-ray diffraction, infrared spectroscopy, atomic absorption spectroscopy, titrometry, and elemental analysis. These studies led to the general conclusion that although the host metal oxide structure is maintained; sodium, magnesium, and zinc insert to only a small extent. Insertion compounds were also made by coulometric titration using non- aqueous cells of the type A(s)/A+(sol)/UOn(s). Open-circuit measurements of the cells at various x-values enabled the free energies of insertion to be calculated, which were then used in a simple model to estimate site binding energies for A. The chemical diffusion coefficients for sodium, magnesium, and zinc determined by the pulse-current method were found to be much lower than those reported for lithium.
