inorganic fluorides include those of cobalt, nickel, and ammonium. "Fuel Cell Components and Their Impact on Performance". "Partial Liquid Ventilation in Adult Patients with Acute Respiratory Distress Syndrome". 196 197 The chemically resistant (but expensive) fluorinated ionomers are used as electrochemical cell membranes, of which the first and most prominent example is Nafion.

Although nitrogen trifluoride is stable, nitrogen requires an electric discharge at elevated temperatures for reaction with fluorine to occur, due to the very strong triple bond in elemental nitrogen; ammonia may react explosively. "Overview on the History of Organofluorine Chemistry from the Viewpoint of Material Industry". 231 The majority of inhaled anesthetics are heavily fluorinated; the prototype halothane is much more inert and potent than its contemporaries. Only in 1886 did French chemist.

Hounshell, David.; Smith, John Kelly (1988). The compound's synthesis, as with xenon hexafluoroplatinate, surprised many chemists. Chemical Principles: The Quest for Insight (4th.). Squires, Roy; Clarke, Arthur., eds. New York: Cambridge University Press. R.; Pizzo,.; Giuliana,. Although fluorapatite (Ca5(PO4)3F) contains most of the world's fluorine, its low mass fraction.5 means that most of it is used as a phosphate. O'Hagan,.; Schaffrath,.; Cobb,. "Safetygram #39 Chlorine Trifluoride" (PDF). "Positron Emission Tomography in Medicine: An Overview".

259 Calcium gluconate is often applied next, providing calcium ions to bind with fluoride; skin burns can be treated with.5 calcium gluconate gel or special rinsing solutions. A b Augenstein. It costs only 58 per kilogram as uranium or sulfur hexafluoride, but many times more as an element because of handling challenges. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. African Americans in Science. 209 210 note 19 Medicinal applications edit Dental care edit Topical fluoride treatment in Panama Main articles: Fluoride therapy, Water fluoridation, and Water fluoridation controversy Population studies from the mid-20th century onwards show topical fluoride reduces dental caries. Chemistry of Arsenic, Antimony and Bismuth.
