Lithium fluoride Chemical Properties,Uses,Production
Description
Lithium Fluoride (LiF) has the lowest refractive index of all common infrared materials. It possesses the highest UV transmission of any material, being able to transmit significantly into the VUV region at the hydrogen Lyman-alpha line (121nm). Lithium fluoride can be applied in rechargeable Li batteries, in radiation dosimeter for personnel monitoring as well as radiation research, as an optical material, as a heat sink material, to produce ceramics, and to dissolve fluid fuel for molten salt reactors.Uses
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.

Chemical Properties
White powderUses
The important uses of lithium fluoride are as flux in glasses, vitreous enamels and glazes; in soldering and welding aluminum; and its prisms in infrared spectrophotometers. The compound also is used for storing solar energy.Uses
As flux for soldering and welding aluminum, in the manufacture of vitreous enamels and glazes. Lithium fluoride prisms are used in infrared spectrophotometers.Preparation
Lithium fluoride is prepared by treating an aqueous solution of lithium hydroxide or lithium carbonate with aqueous hydrofluoric acid: LiOH + HF → LiF + H2O.Purification Methods
Possible impurities are LiCO3, H2O and HF. These can be removed by calcining it at red heat, then pulverizing it with a Pt pestle and storing it in a paraffin bottle. Its solubility in H2O is 0.27% at 18o. It volatilises between 1100-1200o. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 235 1963].Lithium fluoride Preparation Products And Raw materials
