Uranium tetrafluoride precipitation from solutions prepared by electroreduction

The process of uranium tetrafluoride precipitation from solutions strip product solutions after electrochemical reduction was studied. The physicochemical properties of the precipitated uranium tetrafluoride were investigated by various methods. The uranium tetrafluoride precipitated in several different hydrated forms, i.e. UF₄.(0.75-2.5)H₂O. The proportion of UF₄.0.75H₂O in the precipitate increased with increasing temperature. The isotopic and granulometric composition, total content of UO₂ and UO₂F₂, tap density and specific surface area of the obtained uranium tetrafluoride meets specification requirements imposed on this product at the conversion plants.
