Application

Lithium Fluoride is extensively used as a flux in metal welding and brazing due to its ability to lower melting points and improve flow. In the aluminum industry, it serves as a key additive in electrolytic processes to enhance conductivity and efficiency. Additionally, LiF is a critical precursor in the synthesis of lithium salts for batteries and other energy storage applications. Its optical clarity in UV and VUV ranges makes it valuable for lenses, windows, and detectors in spectroscopy and space instrumentation. Researchers also utilize Lithium Fluoride in nuclear reactors as a neutron detector component owing to its favorable nuclear properties.
