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 .
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]
These toxic chemicals are avoided today in consideration of the fact that there are alternative water based, non-toxic heavy liquids like sodium polytungstate solutions. [1] With this relatively new heavy liquid densities up to 3.1 g·cm −3 can be adjusted . Adding parts of pulverulent tungsten carbide increases the density to 4.6 g·cm −3. [2]
Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula W Cl 6. This dark violet-blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. [1]
Molybdenum(V) fluoride is produced by the reaction of molybdenum and molybdenum hexafluoride: [3]. Mo + 5 MoF 6 → 6 MoF 5. It can also be prepared by the reduction of molybdenum hexafluoride with phosphorus trifluoride or tungsten hexacarbonyl, or by the oxidation of elemental molybdenum with fluorine at 900 °C.
