Stannous Fluoride

Stannous Fluoride is a high-purity industrial grade powder with a pH level of 3.8 and 98% purity. It is a compound of tin and fluoride, which offers excellent corrosion resistance and is commonly used in industrial applications. This product is stored at room temperature and is available in powder form. Its purity and pH level make it an ideal choice for industries that require high-quality products.

Both sodium monofluorophophate Na2PO3F and stannous fluoride SnF2 have played an important role in fighting dental decay for the past half century. Whether it is fluoridation of water, or toothpaste or the oral rinse formulations that have been responsible for improved dental health of the population worldwide. The major toothpastes used around the globe contain one of the fluorides NaF, SnF2, or Na2PO3F. Each major toothpaste producer is using NaF and/or Na2PO3F due to their lower costs.

Sodium monofluorophosphate is highly soluble in water (42 g Na2PO3F per 100 g solution). Dilute aqueous solutions of Na2PO3F can be stored indefinitely and its melting point is 625 C.

Sodium monofluorophosphate is produced commercially by fusion of sodium fluoride with sodium metaphosphate.

Commercial production of stannous fluoride is carried out by a reaction between mossy tin and anhydrous HF. It is also prepared by dissolving stannous oxide, SnO, in aqueous HF.
