Abstract

SnAg nanoparticles (SnAg NPs) were prepared by wet synthesis. The chemical composition of the SnAg NPs was messured 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 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.

Abstract (in Czech)

Sn-Ag nanočástice (SnAg NP) byly připraveny mokrou syntézou.Chemické složení SnAg NP bylo stanoveno metodou ICP-MS. Připravené vzorky nanočástic byly charakterizovány metodami elektronové spektroskopie (SEM) a termickou analýzou (DSC). Byly syntetizovány nanočástice s různou velikostí. Závislost bodu tání nanočástic na jejich velikosti byla stanovena experimentálně. Teplota tání nanočástic AgSn byla také vypočtena teoreticky metodou CALPHAD, která byla rozšířena o popis povrchové energie nanočástic.Vlastní experimentální a teoretické výsledky byly porovnány s údaji jiných autorů. Porovnání prokázalo uspokojivou shodu.
