7789-24-4
Lithium fluoride (LiF)
CAS 7789-24-4
Alais: Lithium monofluoride
Molecular formula: FLi
Molecular weight: 25.94
Structural formula:
1.Performance and use
Lithium fluoride is a white powder with a sodium chloride crystal structure. Relative density 2.640, melting point 848 ℃, boiling point 1673 ℃. It begins to evaporate at 1100-1200 ℃, and its vapor is alkaline. Lithium fluoride is slightly soluble in water, but difficult to dissolve in alcohol and other organic solvents. At room temperature, lithium fluoride is easily soluble in nitric acid and sulfuric acid, but insoluble in hydrochloric acid. It can form Li2HF acid salts with hydrofluoric acid.
1: Mainly used in the ceramic industry
2: Widely used in the manufacturing of welding rods, prisms for spectrometers and X-ray monochromators, carriers for proliferation reactions, and lithium-ion battery manufacturing.
