LiF is therefore used in specialized optics for the vacuum ultraviolet spectrum, (See also magnesium fluoride). Lithium fluoride is used also as a diffracting crystal in X-ray spectrometry.Lithium fluoride 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.
In vitreous enamels and glazes, as flux in soldering and welding aluminum, infrared spectrophotometersUsed in specialized UV optics. Also used as a crystal in X-ray spectrometry. Widely employed in PLED (Polymer Light Emitting Diodes) and OLED (Organic Light Emitting Diodes) as a coupling layer to enhance electron injection. Found in liquid-fluoride nuclear reactors. Used to record ionizing radiation in thermoluminescent dosimeters. Component of molten salts.
Volatizes at 1100-1200°Chemically stable compound. Non-hygroscopic in nature.
