Chemical properties: Sodium fluoride is an inorganic compound, its chemical formula is NaF, molecular weight is 41.99g/mol. At room temperature, sodium fluoride is a white crystalline or powdered substance that is easily soluble in water, but almost insoluble in organic solvents such as ethanol and ether. It has a certain corrosive and toxic, excessive intake can cause harm to the human body.
Industrial application: Sodium fluoride is widely used in the surface treatment of stainless steel, aluminum products, batteries and other materials to improve their surface corrosion resistance. In addition, sodium fluoride is also used in the manufacture of fluoride glass, optical glass and other materials, as well as in some industrial production as a catalyst or auxiliary.
Oral health applications: Sodium fluoride is also used in oral health as an additive in products such as toothpaste and chewing gum to prevent dental caries and oral diseases. Sodium fluoride can prevent tooth demineralization, promote tooth remineralization, improve tooth hardness, and thus reduce the incidence of tooth decay. However, excessive intake of sodium fluoride can cause harm to the mouth and body.
