Plutonium hexafluoride is the highest fluoride of plutonium and is of interest for laser enrichment of plutonium in particular for the production of pure plutonium-239 from irradiated uranium. This pure plutonium is needed to avoid premature ignition of low-mass nuclear weapon designs by neutrons produced by spontaneous fission of plutonium-240.It is a red-brown volatile crystalline solid; the heat of sublimation is 12.1 kcal/mol and the heat of vaporization 7.4 kcal/mol.
