NaF
ceramic· NaF
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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
