Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Isotope separation - Wikipedia

A second method of laser separation is known as molecular laser isotope separation (MLIS). In this method, an infrared laser is directed at uranium hexafluoride gas, exciting molecules that contain a U-235 atom. A second laser frees a fluorine atom, leaving uranium pentafluoride which then precipitates out of the gas.Get price

Uranium hexafluoride - Wikipedia

Uranium hexafluoride, colloquially known as "hex" in the nuclear industry, is a compound used in the process of enriching uranium, which produces fuel for nuclear reactors and nuclear weapons. Hex forms solid grey crystals at standard temperature and pressure, is highly toxic, reacts with water, and is corrosive to most metals. The compound reacts mildly with aluminium, forming a thin surface layer of AlF3 that resists any further reaction from the compound.Get price

Is the end coming for sulfur hexafluoride, the most powerful

Oct 15, 2020 · Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6. When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6Get price

Gaseous diffusion - Wikipedia

Gaseous diffusion is a technology used to produce enriched uranium by forcing gaseous uranium hexafluoride (UF 6) through semipermeable membranes. This produces a slight separation between the molecules containing uranium-235 (235 U) and uranium-238 (238 U). By use of a large cascade of many stages, high separations can be achieved. It was the first process to be developed that was capable of producing enriched uranium in industrially useful quantities, but is nowadays considered obsoleteGet price

Grahamlaw - Wikipedia

Rate 1 is the rate of effusion for the first gas. (volume or number of moles per unit time). Rate 2 is the rate of effusion for the second gas. M 1 is the molar mass of gas 1 M 2 is the molar mass of gas 2. Grahamlaw states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight.Get price

Engineering Considerations for Gas Centrifuges – Federation

Since uranium hexafluoride (UF 6) is a corrosive gas, the interior surfaces of the centrifuge need to be resistant to attack and free of organic material, such as grease, hydrocarbon oil from bearings or even human fingerprint oil. This includes not only rotating components such as the rotor, but stationary ones such as feed and extraction piping.Get price
