What purity grades of Sodium Fluoride are available?

Sodium Fluoride is supplied at ≥99% purity in Toothpaste grade for oral care applications and Industrial grade for water treatment, metal processing, and ceramic manufacturing. The Toothpaste grade meets specific particle size and purity standards suitable for dental formulations.

What are the main industrial applications of Sodium Fluoride?

Sodium Fluoride (CAS 7681-49-4) is widely used in water fluoridation for dental health, as a flux in metallurgy and aluminum smelting, in ceramics and glass manufacturing for opacity and durability, and as a chemical intermediate in the production of other fluoride compounds and specialty chemicals.

How does Sodium Fluoride function in water treatment?

In water treatment, Sodium Fluoride is used for controlled fluoridation of drinking water at regulated levels (typically 0.7–1.2 mg/L) to help prevent dental caries. It is also used in industrial wastewater treatment for fluoride ion supplementation and precipitation processes.

What safety precautions should be taken when handling Sodium Fluoride?

Sodium Fluoride is toxic if ingested or inhaled and can cause skin and eye irritation. Proper PPE including gloves, safety goggles, and dust masks should be worn during handling. Work areas should have adequate ventilation. In case of contact, flush with plenty of water and seek medical attention.

What is the difference between Sodium Fluoride and other fluoride compounds?

Sodium Fluoride (NaF) is a simple inorganic fluoride salt with high solubility in water. Unlike Sodium Monofluorophosphate or Stannous Fluoride which are used in toothpaste for enhanced stability, Sodium Fluoride is preferred in industrial applications and water fluoridation for its predictable dissociation and cost-effectiveness.

How should Sodium Fluoride be stored?

Sodium Fluoride should be stored in a cool, dry, well-ventilated area away from acids and moisture. Keep containers tightly sealed when not in use. Under proper storage conditions, the product maintains stability for up to 24 months. Refer to the SDS for detailed storage and handling guidelines.
