Sodium Monofluorophosphate
Molecular formula: Na2PO3F Molecular weight : 143.95
Uses: Used for dental protection efficacy of toothpaste fluoride source, toothpaste abrasives, anticaries agents and desensitizer, general dosage is 0.7-0.76%, but also for the fluoride drinking water, fungicides, and metal surface cleaning agentsIt is also the raw material for preparation of other single-fluorophosphate, also used as a rust inhibitor.
Property: colorless fine crystal or white powder. Decomposition and release of hydrogen fluoride in moist air. Soluble in water, the solution was neutral. Easily hydrolyzed in acidic solution, the thermal decomposition into pyrophosphate, Melting point 625℃.
CAS#: 10163-15-2 Customs No.: 2826909090 MSDS: YF0405-03 Risk No.: Non-dangerous
