Abstract
At 400°, liquid sodium reduces uranium trioxide to the dioxide, no double oxide being present in the product At 600°, the product contains sodium uranate(V), Na3UO4. Thermal analysis indicates that at 540°, sodium oxide and uranium dioxide react to form sodium uranate(V), for which an X-ray powder diffraction pattern is reported, and the reactions in liquid sodium are interpreted on this basis. The oxide U3O8 behaves as a mixture of UO3 and UO2.Keywords
