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

Floating fuel station is a vessel, built under recognized Classification Society. The floating fuel station renders refueling services for yachts, boats, vessels, planes, cars, trucks and other vehicles. The station must have all the vessel Classification documents issued by the Classification Society. There are the stations, built for the ...
The Blackburn B-20 was an experimental aircraft, first flying in 1940, that attempted to drastically increase the performance of flying boat designs. Blackburn Aircraft undertook an independent design study based on a patent filed by their chief designer, John Douglas Rennie [1] for a retractable pontoon float that formed the planing hull.

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
Lithium hexafluorotungstate can be prepared by reacting lithium iodide and tungsten hexafluoride in liquid sulfur dioxide. [3] Physical properties
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 ...
