Lithium fluoride, 99.85% (metals basis), Each

Details

Used in the preparation of hypersensitive thermoluminescent materials, dosimeters and in the room-temperature oxidation of noble metals using fluorine in anhydrous HF. It is mainly used as a component of molten salts. Lithium fluoride forms the basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors. Lithium fluoride is widely used in PLED and OLED as a coupling layer to enhance electron injection. LiF crystals are transparent to short wavelength ultraviolet radiation, more so than any other material. LiF is therefore used in specialized UV optics.
