  • Patent number: 5505927
    Abstract: A process for producing uranium hexafluoride comprises bringing fluorine gas into contact with reactive particles comprising uranium metal, as well as with non-reactive particles which are substantially inert and which are in contact with the reactive particles. The reactive particles are kept distinct from the non-reactive particles. The fluorine gas is allowed to react with the uranium metal at elevated temperature, thereby to produce gaseous uranium hexafluoride. The uranium hexafluoride is separated from any residual fluorine.
