Abstract
Способ получения тетрафторида кремния и октаоксида триурана из тетрафторида урана путем его смешения с диоксидом кремния с последующей термообработкой в воздушной среде, отличающийся тем, что диоксид кремния предварительно подвергают механоактивации в присутствии фторида натрия (0,5-3 масс%.), гомогенизируют с тетрафторидом урана в стехиометрическом соотношении, гомогенизированную шихту гранулируют, сушат при температуре 250-300°C, причем термообработку гранул проводят в среде сухого воздуха в течение 1-2 ч при температуре не выше 600°C.A method of producing silicon tetrafluoride and triuran octaoxide from uranium tetrafluoride by mixing it with silicon dioxide, followed by heat treatment in air, characterized in that the silicon dioxide is subjected to mechanical activation in the presence of sodium fluoride (0.5-3 mass%.), Homogenized with tetrafluoride of uranium in a stoichiometric ratio, the homogenized charge is granulated, dried at a temperature of 250-300 ° C, and the heat treatment of the granules is carried out in dry air for 1-2 hours at a temperature not exceeding 600 ° C.
