The reduction of uranium hexafluoride by carbon tetrachloride
A single stage method is described for converting UF/sub 6/ to UF/sub 4/. UF/sub 6/ dissolves in carbon tetrachloride at ordinary temperatures to form a reasonably stable solution. When heated to temperatures of 150 deg C and above, however, a rapid reaction takes place which is simply expressed as UF/sub 6/ + CCl/sub 4/ -- UF/sub 4/ + Cl/sub 2/ + chlorofluoromethanes. Some excess CCl/sub 4/ is required to take the reaction to completion, and a molar proportion of 4 CCl/sub 4/:1 UF/sub 6/ is satisfactory. Apart from the UF/sub 4/, the products of the reaction are volatile even at ordinary temperatures and can be removed in a stream of warm air. The UF/sub 4/ product is in a form suitable for direct reduction by calcium or magnesium to uranium metal of high quality suitable for fuel element fabrication. (auth)
