Preparation and sublimation of uranium tetrafluoride for the production of thin (UF4)-U-235 targets

摘要

A wet chemical precipitation method to convert triuranium octoxide (U3O8), into uranium tetrafluoride (UF4) has been applied to determine the process yield. In this paper the wet chemical precipitation method is described in detail with a quantitative example and yield calculation. Also the vacuum deposition via sublimation of the uranium tetrafluoride is described and the prepared targets are shown.
