NOTES 75 1 Notes THE DETERMINATION O F URANIUM METAL I N PRODUCTS FROM THE REDUCTIONO F URANIUM OXIDES WITH MAGNESIUM IN the production of uranium metal by the reduction of uranium oxides with magnesium, it is necessary to determine the amount of metal in the reduction product in order to determine the efficiency of the reduction. The reduction product has been shown to contain, as well as uranium metal, significant amounts of uranium oxides (UO, and U,O,), uranium carbides, magnesium uranates, magnesium metal and magnesium oxide. Because of the rather complex nature of this product, a procedure employing either the solubility or insolubility of the metal or the other constituents of the product appeared to offer the most promising approach.The solution of uranium metal in bromineethyl acetate solutions under reflux has been described.1 This solvent system has been found satisfactory for the extraction of uranium metal from samples of reduction products.
