Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air). [2] [3] It is the densest known gas under standard ambient temperature and pressure (298 K, 1 atm). [4]
Macrogol 4000, pharmaceutical quality. Macrogol 3350, often in combination with electrolytes, is used for short-term relief of constipation as well as for long-term use in constipation of various causes, including in multiple sclerosis and Parkinson's disease patients (an often-overlooked non-motor symptom) as well as constipation caused by pharmaceutical drugs such as opioids and ...
Tungsten fluoride may refer to: Tungsten tetrafluoride (tungsten(IV) fluoride) Tungsten pentafluoride (tungsten(V) fluoride) Tungsten hexafluoride (tungsten(VI) fluoride)
Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluid in electronic testers. PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm ...
Tungsten tetrafluoride is an inorganic compound with the formula WF 4. This little studied solid has been invoked, together with tungsten pentafluoride , as an intermediate in the chemical vapor deposition of tungsten films using tungsten hexafluoride .
The reaction of tungsten(VI) oxytetrachloride and hydrogen fluoride will also produce WOF 4. [3] WOCl 4 + 4HF → WOF 4 + 4HCl. WOF 4 can also prepared by the reaction of lead(II) fluoride and tungsten trioxide at 700 °C. [3] 2PbF 2 + WO 3 → WOF 4 + 2PbO. Tungsten(VI) oxytetrafluoride hydrolyzes into tungstic acid. [1] [9] WOF 4 + 2 H 2 O ...
Tungsten(V) fluoride is an inorganic compound with the formula WF 5. It is a hygroscopic yellow solid. It is a hygroscopic yellow solid. Like most pentafluorides, it adopts a tetrameric structure, consisting of [WF 5 ] 4 molecules.
More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it. Examples include glue, adhesive and thickening. Examples of mechanical binders are bond stones in masonry and tie beams in timber framing.
