THE REACTION OF URANIUM DIOXIDE WITH URANIUM HEXAFLUORIDE
The reaction of uranium dioxide with uranium jexafluoride in a quasi- static system has been investigated in the temperature range 25 to 500 C. Although the products of the reaction at 500 C are uranyl fluoride and uranium tetrafluoride, the data indicate that the reaction mechanism is extremely complex, involving littleknown uranium compounds. While these compounds have not been identified or isolated, their presence is deduced from visual observations, weight change and wet chemical and isotopic analyses. A mechanism for the reaction has been proposed which is in agreement with the observed data. This mechanism is not intended as a rigorous representation of the reaction, but rather as an illustration of the experimental results. The reaction of uranium dioxide with uranium hexafluoride apparently proceeds through the formation of a pentavalent oxyfluoride which subsequently undergoes further reaction with the hexafluoride, forming another unstable pentavalent oxyfluoride.
