General description

Ammonium hexafluorophosphate decomposes on heating before melting. Solubility of ammonium hexafluorophosphate in H2O at 20oC is 74.8% w/v. Additionally, it is very soluble in Me2CO, MeOH, EtOH and MeOAc, and is decomposed by boiling mineral acids.

Application

Ammonium hexafluorophosphate is used to synthesize polyethylene oxide based highly conductive non aqueous polymer gel electrolytes exhibiting high conductivity (>10-2S/cm at 25oC)
