naF

Sodium fluoride, with the chemical formula NaF, is an inorganic compound composed of sodium ions (Na+) and fluoride ions (F−). It forms a white, crystalline solid and is highly soluble in water. As with other alkali metal fluorides, NaF has a stable ionic lattice and high melting point.

In medical and public health contexts, NaF is used as a source of fluoride ions to promote dental health. It is included in some toothpastes and mouth rinses and is added to drinking water in controlled amounts to help reduce tooth decay. NaF also serves as a reagent in various chemical syntheses and is employed in metal finishing, glass and ceramic production as a flux or precursor, and in the preparation of other fluoride-containing compounds.

Production of NaF typically involves neutralization of hydrofluoric acid with sodium hydroxide or sodium carbonate, yielding sodium fluoride and water (or related byproducts). It can also be obtained as a byproduct in processes that involve fluorides, such as the industrial production of fluorinated materials and the processing of fluorspar or cryolite in aluminum production.

Safety and handling: NaF is toxic in sufficient quantities and should be handled with care. Ingestion can lead to fluoride poisoning, and exposure to high concentrations can irritate the eyes, skin, and respiratory tract. It is reactive with acids, releasing toxic hydrogen fluoride gas in such reactions. Proper storage, containment, and personal protective equipment are recommended in occupational settings.
