• The addition of bromine to fluorine flow makes it possible to fluorinate UO<SUB>2</SUB> into UF<SUB>6</SUB> even below 200°C, at which temperature fluorination does not proceed with fluorine alone. Presence of bromine corresponding to about 6% of the fluorine concentration is sufficient to induce the fluorination. This effect of bromine is much greater than would be expected from the presence of bromine fluorides in concentrations such as would be produced by direct combination of the fluorine with the added bromine. It appears that the fluorina-tion is enhanced when the mixed gas is held for 320 sec before arriving at the sample. The main component of the reactant gas is BrF<SUB>3</SUB>.
