Molybdenum hexafluoride: MoF 6: 14.5 Theoretical estimates at T = 26.85 °C [19] Tungsten hexafluoride: WF 6: 17.1 Uranium hexafluoride: UF 6: 17.4 Liquids. n-Alkanes
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 .
The metals that make well-characterized hexafluorides include nine metals in the center of the periodic table (molybdenum, technetium, ruthenium, rhodium, tungsten, rhenium, osmium, iridium, and platinum) along with elements 92–94: uranium, neptunium, and plutonium. At room temperature, tungsten hexafluoride is a gas.
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
Tungsten disilicide layers can be prepared by chemical vapor deposition, e.g. using monosilane or dichlorosilane with tungsten hexafluoride as source gases. The deposited film is non-stoichiometric, and requires annealing to convert to more conductive stoichiometric form. Tungsten disilicide is a replacement for earlier tungsten films. [2]
