chemical structure and also properties

NaF crystallizes in the salt chloride motif where both Na+ and F− accounting octahedral coordination sites.<1>

It is usually used as a reagent for the synthetic of fluorides. Representative substrates incorporate electrophilic chlorides consisting of acyl chlorides, sulfur chlorides, and also phosphorus chloride.<2> Like various other fluorides, NaF finds use in desilylation in necessary synthesis.


Fluoride salts are offered widely to improve the toughness of teeth by the development of fluoroapatite, a naturally occurring component of this enamel. In the US, NaF to be once supplied to fluoridate drink water yet its use has been displaced through hexafluorosilicic mountain (H2SiF6) or its sodium salt (Na2SiF6). Toothpaste often has sodium fluoride to prevent cavities.

Sodium fluoride was also used as an antibiotic, as rat poison, and also in ceramics.
