• Detailed Description:

  Cas No. :7681-49-4

  Molecular formula: NaF
  Molecular weight: 41.99

  Property: Whiter off-white powder hardly soluble in water and slightly soluble in alcohol. The PH value of its aqueous solution is a little over 7. It is soluble in hydrofluoric acid.

  Use: Pesticides, corrosion protection for woods, metal fluxing agent, applied to enamel industry and medical industry, it can lower the melting point and improve the weld ripples in the process of cast moulding steel for planer tool; used as the antiseptics for fermentation, as the raw material for making fluorides and cockroach-killer, analytical reagent, etc..

  Quality standard: Enterprise standard and USP24
