Gas-phase synthesis of magnesium nanoparticles: A high-resolution transmission electron microscopy study
Year: 2006
Type: article
Abstract: Magnesium nanoparticles with size above 10nm, prepared by gas-phase syntheses, were investigated by high-resolution transmission electron microscopy. The dominant particle shape is a hexagonal prism terminated by Mg(0002) and Mg{101¯0} facets. Oxidation of Mg yields a MgO shell (∼3nm thick), which has an orientation relation with the Mg. Inhomogeneous facet oxidation influences their growth kinetics resulting in a relatively broad size and shape distribution. Faceted voids between Mg and MgO shells indicate a fast outward diffusion of Mg and vacancy rearrangement into voids. The faceting of polar {220} planes is assisted by electron irradiation.
