Vaporization mechanism from Sn–Ag mixture by Ar–H2 Arc for nanoparticle preparation

The purpose of this paper was to describe the synthesis of Sn–Ag nanoparticles by an arc plasma method. Sn–Ag nanoparticles have been successfully prepared by DC arc plasma with hydrogen addition. The prepared nanoparticles were characterized by X-Ray diffraction, transmission electron microscopy and inductively coupled plasma-atomic emission spectrometry. The obtained results indicated that the nanoparticles have high-purity and spherical shape. The average diameter of the nanoaprticles with 100%-Ar arc was 19.8 nm and that with 50%-H2 arc was 56.5 nm. Another purpose of this work is to investigate the vaporization behavior from molten Sn–Ag mixture with Ar and Ar–H2 arc. We confirmed the vaporization enhancement of Sn from Sn–Ag mixture by hydrogen in arc plasma.
