Description
Greenish-yellow, pungent, corrosive gas. Extremely reactive. Does not occur uncombined in nature.
Uses
Used in refrigerants and other fluorocarbons. Also in toothpaste as sodium fluoride (NaF) and stannous fluoride (SnF2); also in Teflon.
Sources
Found in the minerals fluorite (CaF2) and cryolite(Na3AlF6). Electrolysis of hydrofluoric acid (HF) or potassium acid fluoride (KHF2) is the only practical method of commercial production.
Pronounciation (English)
FLU-eh-reen
