Use

Lithium Fluoride (LiF) is a water insoluble Lithium source for use in oxygen-sensitive applications, such as metal production. It is most widely used as a flux in the production of ceramics, such as enamels, glasses and glazes. Similarly it is also used in brazing and welding fluxes and molten salt chemistry in metallurgy. Lithium fluoride is also used for: X-Ray monochromator plates as an analysis crystal: Lithium fluoride is also used for X-ray monochromator plates where its lattice spacing makes it the most useful analysis crystal. Heat sink materials UV transmission windows: Lithium fluoride is the material with the most extreme UV transmission of all and is used for special UV optics. Lithium fluoride transmits well into the VUV region at the hydrogen Lyman-alpha line (121nm) and beyond.
