uranium hexafluoride

chemical compound

Quick Summary

Uranium hexafluoride (UF6) is a volatile chemical compound of uranium and fluorine. It is a crucial substance in the nuclear fuel cycle, specifically in the process of uranium enrichment.12

Uranium itself is a radioactive chemical element that serves as an important nuclear fuel. Natural uranium consists primarily of two isotopes: uranium-238 and the rarer uranium-235. For use in nuclear reactors, the concentration of uranium-235 needs to be increased, a process known as enrichment.32

Uranium hexafluoride is used in enrichment techniques like gaseous diffusion and gas centrifuging. In gaseous diffusion, UF6 gas is passed through porous barriers, with molecules containing the lighter uranium-235 isotope penetrating slightly faster. Gas centrifuging utilizes high-speed centrifuges to separate the isotopes based on their mass. Uranium tetrafluoride (UF4) is a precursor compound used in the production of uranium hexafluoride.24
