Stoichiometric and X-ray diffraction analysis on the γ2→η' transformation in a dispresant phase silver amalgam

Abstract— Phase composition of an amalgam prepared from a two-particle alloy was determined over a 2-year period by X-ray diffraction. The γ₂content decreased from 3.6% to 0.3%, and η' increased from 3.9% to 10/0%. These alterations in ph content agreed with stoichiometric calculations performed on the basis of the solid state reaction: γ₂+Ag/Cu→η'+γ₁
