SnAg nanoparticles (SnAg NPs) were prepared by wet synthesis. The chemical
composition of the SnAg NPs was obtained by inductively coupled plasma - mass
spectrometry. The prepared fine powder samples were characterized by electron
microscopic technique (SEM) and thermal analysis (DSC). The nanoparticles
with different size were obtained. The size dependent melting point
depression (MPD) of the SnAg NPs was determined experimentally. The size
dependent phase diagram of the SnAg alloy was also calculated using CALPHAD
method, which has been extended to describe the surface energy of SnAg
nanoparticles. The same approach was used for SnAg eutectic MPD calculations.
The own experimental and theoretical results were compared with the data of
the other authors. The satisfactory agreement was found.
