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]
U.S. Domestic: 166 cubic inches per pound (6,000 cm 3 /kg) or 1 ⁄ 6 kg/dm 3 (10 lb/cu ft) (Retail rates only, for all packages. Daily rates only, for packages equal to or less than one cubic foot / 1,728 cubic inches.)
A price index aggregates various combinations of base period prices (), later period prices (), base period quantities (), and later period quantities (). Price index numbers are usually defined either in terms of (actual or hypothetical) expenditures (expenditure = price * quantity) or as different weighted averages of price relatives ( p t ...
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.
