Molecular formula : Na2PO3F
Molecular weight : 143.95
Property : White solid whose melting point is 625°C. Sodium monofluorophosphate accounts for 42% of the saturated solution at 25°C. The PH value of its dilute solution (2%) is 6.5--8. Na2P03F.10H2O can be crystallized from its solution .
Use :Decayed tooth resistant agent and tooth desensitizer. In the ingredients of the toothpaste, it generally accounts for 0.7-0.76%. It has already substituted for sodium fluoride abroad. It is also used to clean the metal surfact and make special glass, as melting agent, etc
