In a process for the preparation of dense, metalgrade UF/sub 4/, the sulfuric acid solution of uranium prepared either from ore of concentrate is treated with a kerosene solution of an amine, the uranium extracted, then stripped from the solvent into hydrochloric acid. Hydrofluoric acid and cupric sulfate are added to the pregnant strip solution and UF/sub 4/ precipitated by bubbling SO/sub 2/ through the hot solution. (J.R.D.) 12340 Equilibrium diagrams for the b- ary systems UF/sub 4/ZrF/sub 4/ and NaF-- ZrF/sub 4/ and the ternary system NaF-ZrF/sub 4/--UF/sub 4/ described in this paper are based on data obtained by thermal analysis differential thermal analysis, equilibration of small samples followed by queuching, visual observations of phase changes and (((((((((Abstract unscannable))))))))))))
