Preparation of Nanocomposite Particles by Gas-Evaporation Technique

Abstract

Iron-nickel and iron-magnesium nanocomposite particles were prepared by evaporation of coat material (nickel or magnesium) onto flying iron nanoparticles, which were produced by gas-evaporation technique. They were studied by means of a transmission electron microscope (TEM) and a scanning electron microscope (SEM) equipped with an energydispersive X-ray analysis system. For the iron-nickel system, the presence of nickel atoms was confirmed only by the analysis with SEM, while for the other one, magnesium particles sticking to chain-like iron particles were observed by means of TEM.
