Electroetching of Dental Amalgam

Journal of Dental Research, 1974
Application of the potentiostatic polarization technique to the metallographic etching of set dental amalgam is described. Etching studies of amalgam prepared from a lathe-cut, a spherical, and a silver-copper dispersed-phase amalgam alloy are reported. The γ 2 phase in set dental amalgam can

Corrosion of Dental Amalgam

Nature, 1972
DENTAL amalgam is incorporated into about 80% of all dental restorations. It is prepared by grinding or triturating a silver–tin alloy (Ag3Sn, the γ phase) with mercury in the proportions 1 : 1 or 5 : 6 of alloy to mercury. The setting reaction of dental amalgam has been studied by many workers1–4 and is now accepted to be
