Potassium fluoride (KF) is an inorganic ionic ceramic compound belonging to the alkali halide family, characterized by a rock-salt crystal structure. It is primarily used in specialized optical, chemical processing, and research applications where its transparency to infrared radiation and chemical stability are advantageous. KF is notable for its role in fluorine chemistry, uranium enrichment processes, and as a component in molten salt systems; it is less common in structural engineering applications compared to other ceramics, but valued in niche industries for its unique combination of optical properties and thermal/chemical resistance.
