Polarization behavior of dental amalgams in 1.0-0.02 M sodium perchlorate solutions were studied by the potential sweep method with a sweep rate of 200 mV/s and potential range of 0.4-1.5V(SCE). The dental amalgam electrodes studied were prepared from a conventional amalgam alloy and three high-copper amalgam alloys according to the manufacturers' instructions in regard to mercury-alloy ratios and trituration times. The dissolution of tin from the conventional dental amalgam increased with the concentration of sodium perchlorate solutions and a current peak of the dissolution was obtained at a concentration of 1.0 M. The oxidation and recuction currents of high-copper amalgams increased with the concentration of sodium perchlorate solutions and the oxidation currents for copper from DJ was observed.
