Molecule of the Week

Uranium hexafluoride

February 28, 2011

Uranium hexafluoride is a white-to-gray solid made by treating any of several uranium-containing materials, including metallic uranium, UC2, UCl5, and UF4, with molecular fluorine. It is covalently bonded, as would be expected from its low sublimation temperature of 56.5 °C. Its main use is separating uranium isotopes. UF6 is stable in dry air but reacts vigorously with water.
