Tungsten hexafluoride was first obtained by conversion of tungsten hexachloride with hydrogen fluoride by Otto Ruff and Fritz Eisner in 1905. [11] [12] WCl 6 + 6 HF → WF 6 + 6 HCl. The compound is now commonly produced by the exothermic reaction of fluorine gas with tungsten powder at a temperature between 350 and 400 °C: [7] W + 3 F 2 → WF 6
At room temperature, tungsten hexafluoride is a gas. 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 ...

"Invisible water" can be created to make it look as if a tin foil boat was floating in the air. Confirmed Adam and Jamie filled a fishtank with sulfur hexafluoride, a gas six times denser than air, and placed a foil boat in it. The resulting buoyancy force was enough to keep the boat from sinking to the bottom. They then filled a small cup with ...
A hexafluoride is a chemical compound consisting of one central atom surrounded by six fluorine atoms. Wikimedia Commons has media related to Hexafluorides . Pages in category "Hexafluorides"
Tungsten(VI) oxytetrafluoride can be synthesized by the reaction of fluorine and tungsten trioxide. [4] It can also be obtained by treating tungsten with a mixture of oxygen and fluorine at high temperatures. [1] Partial hydrolysis of tungsten hexafluoride will also produce WOF 4. [9] WF 6 + H 2 O → WOF 4 + 2 HF
The design of anchor piles allows for three types of mooring configurations—vertical tethers, catenary moorings, and semi-taut/taut moorings—which are used for the mooring of offshore structures such as offshore wind turbines, floating production storage and offloading (FPSO) vessels, floating liquefied natural gas (FLNG) facilities, etc.
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 .
