Lithium Fluoride granules are an inorganic fluoride material supplied in granular form, designed for applications requiring improved handling, controlled feeding, and reduced dust generation. Owing to their high thermal stability, chemical inertness, and wide optical transparency range, LiF granules are widely used in optical coatings, thin-film deposition, electronics, and advanced materials research.
Lithium Fluoride granules feature a stable crystalline structure and uniform chemical composition. Compared with fine powders, the granular form offers better flowability and handling safety, making it suitable for vacuum processes, high-temperature applications, and industrial-scale material processing.
