Research output: Contribution to journalArticle

Abstract

The purpose of this paper was to investigate the growth mechanism of the Sn-Ag nanoparticles prepared by Ar -H2 arc. The effects of the H 2 concentration in the arc, initial composition of raw materials, and gas flow rate of circulation gas on particle diameter was investigated. Numerical analysis was conducted for the growth process with nucleation and co-condensation. Tin vapor was consumed by nucleation and condensation, followed by the condensation of silver vapor. Tin and silver were well synthesized in a liquid state in the co-condensation process since the particles grow at higher temperature than the melting point of Sn-Ag alloy.
