litiumfluorid

Lithium fluoride, with the chemical formula LiF, is an inorganic salt. It is a colorless crystalline solid under standard conditions. Lithium fluoride is sparingly soluble in water but its solubility increases with temperature. It is also soluble in some polar solvents like liquid ammonia. Its melting point is quite high, around 848 degrees Celsius, and its boiling point is 1676 degrees Celsius. This compound crystallizes in the rock salt (sodium chloride) structure.

Lithium fluoride is primarily used in various industrial applications. One significant use is in the production of lithium metal through electrolysis. It also finds application in optics, particularly in the creation of lenses and windows for ultraviolet and infrared spectroscopy due to its transparency across a wide spectrum of light. In dentistry, it has been employed as a fluoride source in some toothpastes and mouthwashes to help prevent tooth decay, though other fluoride compounds are more commonly used today. Lithium fluoride is also a component in some fluxes for welding and brazing, as well as in certain types of glass and ceramics manufacturing. Its low toxicity compared to some other fluoride compounds contributes to its use in these applications.
