Hypostoicheiometric uranium monocarbide-- plutonium monocarbide solid solutions with no impurities detectable by x-ray diffraction oi metallographic examination were prepared by sintering at 1450-1850 deg C mixtures of uranium dioxide, plutonium dioxide, and graphite. Pellets with densities up to 12.85 g/ cm/sup 3/ (94.5 per cent of theoretical density) were achieved by a second sintering of pressed pellets of the reaction product. By a similar procedure single-phase stoicheiometric plutonium sesquicarbide was prepared with pellet densities up to 12.6 g/cm/sup 3/ (99 per cent of theoretical density). However, hypostoicheiometric plutonium monocarbide prepared in the same manner always contained plutonium sesquicarbide as the only impurity, Arc melting of the sintered uranium monocarbide-plutonium monocarbide solid solutions and plutonium sesquicarbide yielded comparably pure materials of near theoretical density. Arc melting of the sintered plutonium monocarbide eliminated the plutonium sesquicarbide impurity resulting in a single-phase hypostoicheiometric plutonium monocarbide. (auth)
