Uranium hexafluoride, sometimes called hex, is an inorganic compound with the formula U F 6. Uranium hexafluoride is a volatile, toxic white solid that is used in the process of enriching uranium , which produces fuel for nuclear reactors and nuclear weapons .
Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
Uranium hexafluoride is the feedstock used to separate uranium-235 from natural uranium. All uranium fluorides are created using uranium tetrafluoride (UF 4); UF 4 itself is prepared by hydrofluorination of uranium dioxide. [6] Reduction of UF 4 with hydrogen at 1000 °C produces uranium trifluoride (UF 3).

Uranyl nitrate is important for nuclear reprocessing.It is the compound of uranium that results from dissolving the decladded spent nuclear fuel rods or yellowcake in nitric acid, for further separation and preparation of uranium hexafluoride for isotope separation for preparing of enriched uranium.
Depleted uranium hexafluoride (DUHF; also referred to as depleted uranium tails, depleted uranium tailings or DUF 6) is a byproduct of the processing of uranium hexafluoride into enriched uranium. [ 1 ] [ 2 ] It is one of the chemical forms of depleted uranium (up to 73-75%), along with depleted triuranium octoxide (up to 25%) and depleted ...
It is most notable as a contaminant in the production of uranium tetrafluoride. [1] As shown by X-ray crystallography, the uranyl (UO 2 2+) centers are complemented by six fluoride ligands. [2] This salt is very soluble in water as well as hygroscopic. It is formed in the hydrolysis of uranium hexafluoride (UF 6): UF 6 + 2 H 2 O → UO 2 F 2 + 4 HF
The key physical process in all of them is an infrared laser, which vibrationally excites only one of the isotopes in gaseous uranium hexafluoride. This requires a wavelength near 16 μm. Traditional MLIS then continued to excite the molecules unto dissociation, at which point they crystallized as uranium-235 pentafluoride.
