WebFluorite mining (the main source of fluorine) was estimated in 2003 to be a $550 million industry, extracting 4.5 million tons per year. [4] Mined fluorite is separated into two main grades, with about equal production of each. Acidspar is at least 97% CaF 2; metspar is much lower purity, 60–85%.
WebFKM is a family of fluorocarbon -based fluoroelastomer materials defined by ASTM International standard D1418, [1] and ISO standard 1629. [2] It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. [3] All FKMs contain vinylidene fluoride as a monomer. WebFluoride ( / ˈflʊəraɪd, ˈflɔːr -/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F− (also written [F]− ), whose salts are typically white or colorless.

WebOxygen difluoride is a chemical compound with the formula OF2. As predicted by VSEPR theory, the molecule adopts a "bent" molecular geometry. It is strong oxidizer and has attracted attention in rocketry for this reason. With a boiling point of -144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [5]
Fluorine (9F) has 18 known isotopes ranging from F to F (with the exception of F ) and two isomers ( F and F ). Only fluorine-19 is stable and naturally occurring in more than trace quantities; therefore, fluorine is a monoisotopic and mononuclidic element. The longest-lived radioisotope is F ; it has a half-life of 109.734(8) min. All other fluorine isotopes have half-lives of less than a minute, and most of those less than a second.
