Hot pressed and vacuum sintered specimens of is the more promising of the two techniques, has yielded specimens with a maximum density of 12.5 g/cm/sup 3/. Uranium mononitride was made by hydriding uranium chips followed by nitriding at 1400 to 1500 deg C with nitrogen gas. The nitriding was followed by a thirty minute soaking period in argon before cooling in argon to insure the decomposition of the higher nitrides. A complete range of solid solution was found to exist between UC and UN. The lattice parameter change versus the composition of the solid solution deviated only slightly from Vegard's law. The existence of solid solutions of U(C,N,O) was indicated by several reactions of UN with U(C/sub 0.75/O/sub 0.25/, and chemical analyses are being made to check these results. (auth)
