A molecule of uranium hexafluoride contains six atoms of fluorine for every atom of uranium. In order to obtain this molecule, one first produces molecules of uranium tetrafluoride - containing four atoms of fluorine per uranium atom. In a second step the tetrafluoride is transformed into hexafluoride. The photograph shows a view of the Comurhex-Pierrelatte factory where the tetrafluoride to hexafluoride transition takes place. The manufacture and use of this highly corrosive substance require strict safety precautions as well as highly specialised equipment.
