Through the use of anodic polarization studies in Ringer's solution, the electrochemical behavior of γ 1 phase of dental amalgam (Ag2Hg3) and γ 1 containing dissolved tin is compared with that for the γ 2 phase in dental amalgam (Sn7-8Hg). The results indicate that when tin is dissolved in γ1 it does not affect the electrochemical behavior of that phase.
