CO OZNACZA SŁOWO URANIUM HEXAFLUORIDE
Heksafluorek uranu
Heksafluorek uranu, zwany "heksem" w przemyśle jądrowym, jest związkiem stosowanym w procesie wzbogacania uranu, który wytwarza paliwo do reaktorów jądrowych i broni jądrowej. Tworzy stale szare kryształy w standardowej temperaturze i pod ciśnieniem, jest bardzo toksyczny, reaguje gwałtownie z wodą i koroduje większość metali. Powolnie reaguje z aluminium, tworząc cienką warstwę powierzchniową AlF3, która opiera się dalszemu reakcjom.
