Uses
Atomic fluorine and molecular fluorine are used for plasma
etching in semiconductor manufacturing, flat panel display
productions and MEMS fabrication. It is also used in the
productions of low frictions plastics like teflon and halon, freon.
Fluorohydrocarbons are used in air-conditioning and in
refridgeration.
Interesting things to know about fluorine
Fluroides are often added to toothpaste and muncipal water
supplies to prevent dental cavities.Annual world production of the
mineral fluorine is 4 million tonenes.Fluorine occurs naturally in
the earths crust where you can find it id rocks, coal and clay
air.Small amounts of fluorine are naturally present in water,
plants, and animals.
