What is Sodium Fluoride?
- Sodium Fluoride is a corrosive, hygroscopic, and moderately toxic inorganic fluoride. Its CAS No. is 7681-49-4. Its aqueous solution has a slow corrosive effect on glass.
- Sodium Fluoride powder is a multifunctional industrial raw material and fluorine source. Its price is relatively low compared to other fluorides, and it is not easily deliquescent, giving it an unshakeable and important position. It can be used as a preservative, sealing material, insecticide, and whitening toothpaste.
- Optical grade Sodium Fluoride has the highest purity (4N and above) and the most significant technological barriers among all Sodium Fluoride grades. Its purity is far higher than that of industrial grade and reagent grade Sodium F It can be used in high-end fields such as fluoride optical fibers and optoelectronics.
