Editing Uranium hexafluoride (section)

==Preparation==
[[Uranium dioxide]] is converted with [[hydrofluoric acid]] (HF) to [[uranium tetrafluoride]]:<ref name=Ull>{{cite book |doi=10.1002/14356007.a27_281.pub2 |chapter=Uranium, Uranium Alloys, and Uranium Compounds |title=Ullmann's Encyclopedia of Industrial Chemistry |date=2007 |last1=Peehs |first1=Martin |last2=Walter |first2=Thomas |last3=Walter |first3=Sabine |last4=Zemek |first4=Martin |isbn=978-3-527-30385-4 }}</ref>
:{{chem2|UO2  +  4 HF  ->  UF4  + 2 H2O}}
In samples contaminated with [[uranium trioxide]], the [[oxyfluoride]] is produced in the HF step:
:{{chem2|UO3  +  2 HF  ->  UF2O2  +  H2O}}
The resulting {{chem2|UF4}} is subsequently oxidized with [[fluorine]] to give the hexafluoride:
:{{chem2|UF4  +  F2  ->  UF6}}
