Uses of Fluorine

Fluorine is a pale yellow or brown gas that is highly corrosive. Here are some of the more common uses of fluorine in the world today.

Uses of Fluorine

  • Some compounds of fluorine (such as sodium fluoride, stannous fluoride and sodium MFP) are added to toothpastes to prevent dental cavities. These are now regularly added to water as well.
  • Most general anesthetics are derived from compounds of fluorine.
  • Fluorine-18 emits positrons and has a relatively large half-life. This makes it ideal for use in positron emission topography.
  • Anti-reflective coatings contain compounds of fluorine.
  • Fluorine can be used for plasma etching, flat panel display and MEMS (microelectromechanical) fabrication.
  • HF (hydrofluoric acid) is used to etch glass, usually in light bulbs.
  • Fluorine is used in one step of the production of halons such as freon.
  • Fluorine is used to obtain pure uranium from uranium hexafluoride.
  • Compounds of fluorine are used in refrigeration and air-conditioning systems.
  • Another compound of fluorine is used in the electrolysis of aluminum. This process allows pure aluminum to be obtained!
  • A who family of broad-spectrum antibiotics (these work on a number of different bacteria) contain fluorine.
  • Much commercially produced fluorine is used to make sulfur hexafluoride. This compound is used as a dielectric medium in the electrical industry.
