Abstract

A dense uranium-carbon compound, which may also contain plutonium, is produced by cold-compacting and sintering a mixture of uranium and carbon powders (with or without plutonium) containing also iron in the form of UFe2 or U6Fe, the iron forming 1 to 10% by weight of the mixture. It is stated that, when using UFe2, maximum density is obtained when the carbon and uncombined uranium contents of the starting mixture are in stoichiometric proportions to form uranium monocarbide. Specifications 821,287, 825,041 and 914,153 are referred to.ALSO:A dense uranium-carbon alloy, which may also contain plutonium, is produced by cold-compacting and then sintering at not less than 800 DEG C. a mixture of uranium and carbon powders (and, if desired, plutonium powder) containing also iron in the form of an intermetallic compound of uranium and iron, the iron forming 1-10% by weight of the mixture. The compound may be UFe2 or U6Fe, use of the latter being limited to iron contents of less than 3.8%. Heating of the compact is preferably carried out rapidly as described in Specification 914,153. In examples described uranium powder of less than 300 mesh was mixed with ultrafine graphite and the mixture then mixed with UFe2. The resultant mixture was cold-compacted at 60 tons/sq. inch, then passed rapidly into a vacuum furnace at 1100 DEG C. The compacts were estimated to reach a maximum temperature of 1200-1450 DEG C. within a few minutes, and were then heated at 1100 DEG F. for two hours. Specifications 821,287 and 825,041 are referred to.
