Uranyl fluoride Specification

 Uranyl fluoride ,its cas register number is 2445-07-0. It also can be called Uranium oxyfluoride ; Uranium, difluorodioxo-, (T-4)- ; and Uranyldifluoride . Uranyl fluoride (CAS NO.2445-07-0) is an intermediate in the conversion of uranium hexafluoride UF6 to an uranium oxide or metal form, and is reported to be stable in air to 300 °C. The reaction( UF6+ 2H2O → UO2F2+ 4HF) can take place whether it is a solid or a gas, but will take place almost instantaneously when the UF6 is in a gaseous state. Its chemical hazards are far more significant than radioactive hazards.
