A PROCESS FOR THE PREPARATION OF URANIUM FLUORIDE
A simple method is given for producing UF/sub 4/ from ammonium uranate. In this method, gaseous ammonium fluoride or ammonium bifluoride is passed over ammonium uranate in an oven at 500 to 700 deg C for 1 to 2 hr. The reaction is 3(NH/sub 4/)/sub 2/U/sub 2/O/sub 7/ + 24 NH/sub 4/F -6 UF/sub 4/ + 21 H/sub 2/O + 2 N/sub 2/ + 2 6 NH/sub 3/. The gases issuing from the oven are treated to recover the ammonia and any ammonium fluoride. After the reaction is completed, an inert gas is passed into the oven for a few minutes to cool the product and to remove the ammonium fluoride residues. The advantages of this method are its simplicity, reduced time required for operation, no involvement of expensive or dangerous chemicals, and yields of approximately 99%. (D.L.C.)
