Chemical Properties Of Lithium Fluoride Cas 7789-24-4

Lithium fluoride is an inorganic fluoride with the chemical formula LiF and a molecular weight of 25.94. It forms white crystals in the cubic crystal system (NaCl-type structure) and appears as a white powder or fine granules at room temperature. It has a high melting point and is highly chemically stable; it is slightly soluble in water, insoluble in organic solvents, and soluble in hydrofluoric acid to form lithium hydrofluoride. Its core applications include raw materials for lithium-ion battery electrolytes, optical materials, molten salt carriers in the nuclear industry, and metallurgical additives, making it a key foundational material for new energy and high-end manufacturing.
