Investigations on Methods of Producing Crystalline Ammonium-Urany 1 Carbonate and its Applicability for Production ofnUranium-Dioxide Powder and Pellets

摘要

A method for the production of crystalline ammonium-uranyl car-bonate is described. On account of its simple synthesis and its chemical composition, this substance is a suitable intermediate product in the mak-ing of uranium-dioxide powder for reactor fuel.nExperimental data for the precipitation of ammonium-uranyl car¬bonate are presented. The density and dimensions of the uranium-dioxide pellets made from the precipitate are indicated and the results evaluated.
