[0002] Lithium fluoride is an inorganic salt with the chemical formula LiF and a molecular weight of 25.94. It is an alkali metal halide, a white crystal at room temperature, and slightly soluble in water. It is used in the nuclear industry, enamel industry, optical glass manufacturing, desiccant, flux, etc. With the progress of science and technology, the requirements for lithium fluoride are getting higher and higher. Therefore, how to prepare lithium fluoride with better performance is not only the need of scientific and technological progress but also the current market demand. In industrial production, the neutralization method is mostly used for preparation.
