制备方法与用途

生产方法

制备四氯化二铀(UO₂Cl₂)的方法为:UCl₄ + O₂ → UO₂Cl₂ + Cl₂。

将硼硅酸玻璃反应管置于卧式管式炉中,进行抽真空处理,或在300~350℃下边通干燥氮气边加热1小时。随后,在石英舟中放入9.7g(0.025mol)无水四氯化铀,并迅速送入反应管内。接着将系统抽真空,再通入干燥氧气,使炉温升至300~350℃,在不断导入氧气的条件下加热7小时。之后,待温度降至室温后停止供氧,立即将反应管移入含有干燥气氛的干燥箱中,并密封保存。

上述化学反应理论上是定量进行的;但由于产物可能黏附于反应舟上,实际产量会略有减少。

  • Kinetics of dissolution of stoichiometric uraninite
    作者:V. V. Ivanov、I. B. Popov

    日期:2011.4
    The kinetics of dissolution of stoichiometric uraninite (UO2.) synthesized by electroreduction (electrolysis) of uranyl chloride in a melt of an eutectic mixture of alkali metal salts was studied. It follows from the results obtained that, in the initial step of uraninite dissolution under both dynamic and static conditions, schoepite is not an intermediate phase. It is formed, apparently, in the further steps by oxidation of uranium dioxide. The diffusion coefficients of uranium in solutions over uraninite and schoepite were determined. It was found that, at least in the initial step of the dissolution, the forming uranyl hydroxide occurs in the solution either in the dissociated state or in the form of mononuclear hydroxo complexes.
