Uranium-aluminum compounds were prepared by solidsolid reaction of aluminum powder and uranium hydride; x-ray-diffraction patterns showed that single phases of UAl/sub 2/, UAl/sub 3/, and UAl/sub 4/ could be achieved. The uranium-beryllium compound, UBe/sub 1//sub 3/, was prepared by solid-solid reaction of berylllum powder and uranium hydride. The uranium-boron compounds, UB/sub 2/ UB/sub 4/, and UB/sub 1//sub 2/ were prepared by solid reaction, and single borides were obtained; carbon contamination was especially serious in these samples. The uranium-carbon compounds, UC and UC/sub 2/, were prepared by solid-solid reactlons to 1200 deg C; the x-ray-diffraction patterns showed a mixture of phases, and higher temperatures are probably required. The uranium- nitrogen compounds, UN and UN/sub 2/, were prepared by reaction of uranium with ammonia at 850 deg C for UN/sub 2/ and subsequent heating of that product in vacuum for UN. The uranium-selenium compounds, USe and USe/sub 2/, were prepared in very small samples; the violence of the reaction of selenium with uranium hydride and the lack of availability of hydrogen selenide limits the size of preparations. The uranium-silicon samples, USi/sub 2/ and USi/sub 3/ were prepared by solid-solid reaction of UH/sub 3/ and 8i; numerous attempts were made to prepare U8i. One of the USi/sub 2/ samples was alpha -USi/sub 2/ and the other was beta -USi/sub 2/. The uranium-sulfur compounds, US and US/sub 2/, were prepared; US/sub 2/ was prepared by forming unanium hydride in a flow furnace and then reacting the hydride with hydrogen sulfide; US was prepared by reacting some of the US/sub 2/ with UH/sub 3/.
