Sodium fluoride (NaF) is an ionic ceramic compound composed of sodium and fluoride ions in a rock-salt crystal structure. It is primarily used in dental products (toothpastes and fluoride treatments) for its proven efficacy in preventing tooth decay and strengthening enamel. Beyond dentistry, NaF serves as a precursor material in fluorine chemistry, an anti-caking agent in food-grade salt, and has research applications in nuclear fuel processing and as a molten-salt coolant in advanced reactor designs; engineers select it when fluoride ion delivery or high-temperature fluorine chemistry is required.
