The hydrolyzation reaction and thermal transformation of UF4/KBr in air at ambient temperatures were studied by in-situ transmission Fourier transform infrared (FT-IR) spectroscopy. The infrared spectra for a series of different compounds containing uranium before and after reaction were obtained. Following hydrolysis of UF4/KBr in air, the primary products were UO2F2 and their hydrolysates. Other products, including U3O8, UO2, and UO3, appeared with increased reaction time. During the heating process, the hydrolysates of UF4/KBr reacted with each other, finally yielding only uranium oxides.
