Selenium hexafluoride is the inorganic compound with the formula SeF 6. It is a very toxic colourless gas described as having a "repulsive" odor. [ 5 ] It is not widely encountered and has no commercial applications.
Pentafluoroselenium hypofluorite can also formed from selenium oxyfluoride and fluorine gas in the presence of potassium fluoride. [4] [5] SeOF 2 + KF → K + [SeOF 3] − — F 2 → K + [SeOF 5] − — F 2 → KF + SeOF 6. The reaction of fluorine gas and Hg(OSeF 5) 2 produces SeOF 6 in much higher yield and with less SeF 6. [3]

In comparison with its sulfur counterpart (sulfur hexafluoride), selenium hexafluoride (SeF 6) is more reactive and is a toxic pulmonary irritant. [11] Some of the selenium oxyhalides, such as selenium oxyfluoride (SeOF 2) and selenium oxychloride (SeOCl 2) have been used as specialty solvents. [5]
A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+. Many molecules fit this formula. 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 .
Rihanna is a style icon. Full stop. But as such, the Savage x Fenty founder, who won the CFDA Fashion Awards' Fashion Icon Award in 2014, occasionally gets compared to fictionalized characters ...
This is mainly uranium hexafluoride, containing the uranium-233 fuel, but also neptunium hexafluoride, technetium hexafluoride and selenium hexafluoride, as well as fluorides of some other fission products (e.g. iodine, molybdenum and tellurium). The volatile fluorides can be further separated by adsorption and distillation.
