Uranium was successfully cast at temperatures as high as 1900 to 2000 deg C in crucibles made from CeS, CeS/sub 1.38/, ThS, ThS/sub 1.75/, and ThU/sub 0.7/S/sub 2/ with the sulfur pickup in all cases less than 0.15 wt.%, in some cases at low temperatures being less than 0.005%. A summary of actual sulfur absorption for different experimental temperatures and crucible types is given. The effect of the molten mixture of U and UBr/sub 3/(Br/U =2) upon some sulfide refractories was investigated. The results indicate that only ThS/sub 2/ and divalent sulfides like ThUS/sub 2/, US, ThS, etc., would withstand the U--UBr/sub 3/ mixture. Uranium may be separated from metal salt mixtures (CaCl/sub 2/, SrBr/ sub 2/, BaI/sub 2/, etc.) by distillation of the salt and fusion of the U in a sulfide crucible. (auth)
