Abstract: The hydroiyzation 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.
