    en.wikipedia.org/wiki/Fluorochemical_industry

    For countries with available data (free-market countries), about 17,000 metric tons of fluorine are produced per year by 11 companies, all G7-resident. [27] Fluorine is relatively inexpensive, costing about $5–8 per kilogram ($2–4 per pound) when sold as uranium hexafluoride or sulfur hexafluoride.

    Fluorine is the 13th most abundant element in Earth's crust at 600–700 ppm (parts per million) by mass. [61] Though believed not to occur naturally, elemental fluorine has been shown to be present as an occlusion in antozonite, a variant of fluorite. [ 62 ]

    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]

    The solubility in acetone is 0.0036 g/kg at 18 °C and 0.0039 g/kg at 37 °C. [6] The standard enthalpy of formation of rubidium fluoride is Δ f H 0 298 = −552.2 kJ mol−1, [7] the standard free enthalpy of formation ΔG 0 298 = −520.4 kJ mol−1, [7] and the standard molar entropy S 0 298 = 113.9 J K −1 ·mol−1.
