Abstract

1473075 Uranium fluorides KERNFORSCHUNG mbH GES FUR 7 Jan 1976 [6 Feb 1975] 453/76 Heading C1A [Also in Division C7] Deposits in plant handling UF 6 are removed by reaction with IF 7 at temperatures of 20‹ C. or higher. The deposits are of UF 5 , or lower fluorides, e.g. UF 4 , U 2 F 9 , U 4 F 17 which are initially converted to UF 5 by the IF?, the reaction between UF 5 and IF 7 producing UF 6 and IF 5 which are removed as gases.
