Synthesis and Morphological Control of UO₂F₂ Particulates.

ABSTRACT: Uranium-based microspheres are of interest due to their potential applications as targets for medical isotopes production, as fuel for nuclear reactors, and as standardized materials for nuclear forensics. Here, for the first time, UO₂F₂ microspheres (1-2 μm) have been prepared from the reaction between UO₃ microspheres and AgHF₂ in an autoclave. In this preparation, a new fluorination method has been applied, and HF_(g)-produced in situ from the thermal decomposition of AgHF₂ and NH₄HF₂-was used as the fluorinating agent. The microspheres were characterized by powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM). Diffraction results indicated that the reaction performed with AgH
