what is fluorine used for?

Answer 1

Lots of things...

Additive in toothpaste, water supplies, functional group in many molecules that serve as drugs, teflon has a lot of fluorine in it...I could go on for days...

Answer 2

Fluorine-containing compounds are used to increase the fluidity of melts and slags in the glass and ceramic industries. Fluorspar (calcium fluoride) is introduced into the blast furnace to reduce the viscosity of the slag in the metallurgy of iron. Cryolite, Na2AlF6, is used to form the electrolyte in the metallurgy of aluminum. Aluminum oxide is dissolved in this electrolyte, and the metal is reduced electrically from the melt. The use of halocarbons containing fluorine as refrigerants was patented in 1930, and these volatile and stable compounds found a market in aerosol propellants as well as in refrigeration and air-conditioning systems. However, use of fluorocarbons as propellants has declined sharply because of concern over their possible damage to the ozone layer of the atmosphere. A use for fluorine that became prominent during World War II is in the enrichment of the fissionable isotope 235U; the most important process employed uranium hexafluoride. This stable, volatile compound was by far the most suitable material for isotope separation by gaseous diffusion.

While consumers are mostly unaware of the fluorine compounds used in industry, some compounds have become familiar to the general public through minor but important uses, such as additives to toothpaste and nonsticking fluoropolymer surfaces on frying pans and razor blades (for example Teflon).

Answer 3

Fluorine is used in the production of steel and aluminum.
Highly volatile, it is a very dangerous albeit organic compound

Answer 4

as a poison, ingredient of teflon as mineral cryolite to lower melting point of bauxite (aluminum ore)

Answer 5

dont know but it helps your teeth not get cavities.

Answer 6

whitening
