The UN pellets to be sintered were placed in a tantalum container which was sealed in a plastic bag. The bag and contents were placed in an inert atmosphere at 1800 deg C. No improvement in density was obtained over the previously reported 91 to 93% of theoretical. In the preparation of UC from ammonium diuranate and C, good results were obtained by the addition of the theoretical amount of C needed to react with the UO/sub 2/ formed by the decomposition of ammonium diuranate. The eilects of variation in furnacing on the product are discussed. Experiments on the fabrication of UC from hot- pressing U metal powder and C revealed insufficient intimate mixing. Pellets of U/sub 3/Si/sub 2/ of 95% theoretical density were fabricated by cold-pressing and sintering. X-ray-diffraction analysis indicated some pickup of oxygen. (3ee also ORO-254.) (C.J.G.)
