Corrosion of zinc-containing dental amalgam.

The gamma 1 lattice constant of amalgams with and without zinc kept under corrosive and non-corrosive conditions was determined at different times after trituration. Zinc disappeared during 1 d from the gamma 1 phase of an amalgam made from 0.9% Zn alloy and during 30 d from an amalgam made from 4% Zn alloy, when powdered amalgam was in contact with a 1% NaCl solution.
