Uranium hexafluoride (UF6) is a chemical compound composed of uranium and fluorine. It is a colorless, odorless gas at high temperatures but can be solid or liquid at lower temperatures. UF6 is primarily used in the nuclear industry for the enrichment of uranium, which is essential for fuel in nuclear reactors and for the production of nuclear weapons. The process of uranium enrichment involves converting uranium ore into UF6, which can then be processed in gas diffusion or gas centrifuge methods. This compound is significant because it allows for the separation of isotopes, particularly Uranium-235 and Uranium-238, which have different nuclear properties.
