THE CARBOTHERMIC REDUCTION OF URANIUM OXIDE
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 the metal. As carried out on the 100-pound scale, the average over-all yield of uranium from 21 reductions was 31.2% per reduction cycle. The uranium is of high purity and is in a form that is well suited to direct arc melting with or without alloying, clad rolling, or powder metallurgical consolidation. (auth)
