X‐ray analysis of α‐, β‐, and γ‐phase Ag–Hg alloy films produced on polymer substrates by casting polyacrylamide–AgNO3aqueous solution in Hg atmosphere

摘要

AbstractIt is reported that, by dropping Hg metal on the wet α‐phase Ag–Hg alloy film formed on the cast polyacrylamide–AgNO3aqueous 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 fi
