Abstract
Способ получения двуокиси урана электролизером расплава электролита, содержащего эвтектическую смесь хлоридов щелочных и щелочноземельного металлов и соединения урана, отличающийся тем, что, с целью снижения коррозионной активности двуокиси урана, электролиз ведут в потенциостатическом режиме при катодном потенциале - 1,2 ... 1,3 В относительно хлорного электрода сравнения в атмосфере инертного газа и в качестве хлорида щелочноземельного металла в эвтектической смеси электролита используют хлорид бария, а в качестве соединений урана - тетрахлорид и двуокись урана при следующем соотношении компонентов электролита, мас.%:UCl- 5 - 15UO- 5 - 15Эвтектическая смесь BaCl- NaCl - KCl - ОстальноеA method of producing uranium dioxide by an electrolyzer of an electrolyte melt containing a eutectic mixture of alkali and alkaline earth metal chlorides and uranium compounds, characterized in that, in order to reduce the corrosivity of uranium dioxide, electrolysis is carried out in a potentiostatic mode at a cathode potential of 1.2 ... 1, 3 V relative to the chloride electrode of comparison in the atmosphere of inert gas and as an alkaline earth metal chloride in a eutectic mixture of electrolyte, barium chloride is used, and as uranium compounds — t trahlorid and uranium dioxide of the electrolyte with the following ratio of components, wt%:. UCl- 5 - 15UO- 5 - 15Evtekticheskaya mixture BaCl- NaCl - KCl - Other
