Among all common infrared materials, the refractive index of lithium fluoride (LiF) is very low. It also has the highest UV transmittance of all materials, and can significantly transmit to the VUV region at the Lyman-Alpha hydrogen line (121nm).
It is slightly soluble in water and soluble in acids such as HDF. However, it can be cleaned with alcohol.
Lithium fluoride is a very widely used flux in ceramic production, such as enamel, glass and glaze. Similarly, it is also used in brazing and welding fluxes and molten salt chemistry in metallurgy.
It is also used for:
*X-ray monochromator plate as analysis crystal
*Heat sink material
*UV transmission window
