Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Fluorine's chemistry includes inorganic compounds formed with hydrogen, metals, nonmetals, and even noble gases; as well as a diverse set of organic compounds. [note 1] For many elements (but not all) the highest known oxidation state can be achieved in a fluoride. For some elements this is achieved exclusively in a fluoride, for others ...
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
FLiNaK is the name of the ternary eutectic alkaline metal fluoride salt mixture LiF-NaF-KF (46.5-11.5-42 mol %). [1] It has a melting point of 462 °C [ 2 ] and a boiling point of 1570 °C. It is used as electrolyte for the electroplating of refractory metals and compounds like titanium , tantalum , hafnium , zirconium and their borides . [ 3 ]

NaK with 77% potassium is eutectic and has the lowest melting point of the NaK alloys at −12.6 °C. [78] Liquid sodium is used as a heat transfer fluid in sodium-cooled fast reactors [79] because it has the high thermal conductivity and low neutron absorption cross section required to achieve a high neutron flux in the reactor.
