The anodic behaviour of massive and dental amalgam alloys in artificial saliva containing different concentrations of Cl − or F − ions has been studied. Quantitative relations could be established between concentrations of these ions and the height of the peaks corresponding to anodic oxidation of Sn or Ag. Contrary to f − , Cl − ions from Ag complexes via AgCl which excess cl − ions. The massive alloy is stable below 0.15 V. Calcium fluoride can be safely admixed with dental amalgam alloy without enhancing its corrosion.
