sodium fluoride

[′sōd·ē·əm ′flu̇r‚īd]
(inorganic chemistry)
NaF A poisonous, water-soluble, white powder, melting at 988°C; used as an insecticide and a wood and adhesive preservative, and in fungicides, vitreous enamels, and dentistry.

Sodium Fluoride

 

NaF, a salt; colorless crystals. Density, 2.79 g/cm3; melting point, 992°C. Solubility in water, 3.90 percent at 20°C and 4.83 percent at 100°C. Sodium fluoride occurs naturally as the mineral villiaumite. It is prepared industrially by roasting fluorspar with soda and silica (according to the reaction CaF2 + Na2CO3 + Si02 = 2NaF + CaSiO3+ CO2), as well as by other methods. It is used as a wood preservative and sometimes as an insecticide; it is a component of enamels. Sodium hydrofluoride, NaHF2, is a component of fluxes in aluminum soldering.
