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 .
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).
Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6), which is a byproduct of the mining of phosphate rock. In the nuclear industry, uranium hexafluoride (UF 6) is an important intermediate in the purification of this element.
Gaseous diffusion uses microporous membranes to enrich uranium. Gaseous diffusion is a technology that was used to produce enriched uranium by forcing gaseous uranium hexafluoride (UF 6) through microporous membranes. This produces a slight separation (enrichment factor 1.0043) between the molecules containing uranium-235 (235 U) and uranium ...
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2732–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7210%), and uranium-234 (234 U, 0.0049–0.0059%).
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 ...
Molybdenum hexafluoride and rhenium hexafluoride are liquids. The rest are volatile solids. Uranium hexafluoride in sealed glass. Metal hexafluorides are oxidants because of their tendency to release fluorines: for example, platinum hexafluoride was the first compound to oxidize molecular oxygen [68] and xenon. [69]
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 ...
