la production de fluorine

  • Fluorine - Wikipedia

    Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions.As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.. Among the elements, fluorine ranks 24th in universal abundance and 13th in ...

    This process consumes about 75% of the world fluorine production. The second most important product is sulfur hexafluoride, SF 6, a valuable gaseous insulator in high voltage equipment. Fluorine is also used to produce fluorocarbons which are chemically inert, thermally stable and non-flammable.

  • Fluorine-18 Production – 18f-fdg

    May 24, 2016 · The relatively long half-life of fluorine-18, 110 minutes, means that the isotope can be delivered to nuclear medicine departments up to a few hundred kilometres away from the production site. This is useful in fluorine-18 production because it eliminates the need for a cyclotron to be located on-site at each PET facility.
