    en.wikipedia.org/wiki/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]

    en.wikipedia.org/wiki/Sodium_tungstate

    Sodium tungstate is obtained by digestion of tungsten ores, the economically important representatives of which are tungstates, in base. Illustrative is the extraction of sodium tungstate from wolframite: [1] Fe/MnWO 4 + 2 NaOH + 2 H 2 O → Na 2 WO 4 ·2H 2 O + Fe/Mn(OH) 2. Scheelite is treated similarly using sodium carbonate.

    en.wikipedia.org/wiki/Tungsten(IV)_oxide

    Tungsten(IV) oxide is the chemical compound with the formula W O 2. The bronze-colored solid crystallizes in a monoclinic cell. [1] The rutile-like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). [1] Each tungsten center has the d 2 configuration, which gives the material a high electrical ...
