THE CARBOTHERMIC REDUCTION OF URANIUM OXIDE
, 1957 Uranium oxide has been reduced by carbon under vacuum at 225O deg C, to yield a product consisting of dendritic uranium carbide in a matrix of uranium. Uranium sponge is obtained from this cermet by hydrolyzr-ng the interconnected UC. This is followed by pickling in dilute nitric acid to remove the residual hydrolysis product UO/sub 2/ x H/sub 2/O from
