It is reported that, by dropping Hg metal on the wet α‐phase Ag–Hg alloy film formed on the cast polyacrylamide–AgNO 3 aqueous solution, the α phase of fcc structure can be converted into other phases that contain more Hg. The X‐ray analysis of these phases reveals that they are the β phase of hexagonal structure and the γ phase of bcc structure. It is also shown that the lattice constant of the α phase can be controlled to some extent by pH of the aqueous solution of PAAm from which the alloy film is formed.
