Metal atom clustering in reduced lead-, bismuth- and antimony-silicate glasses: a comparative molecular dynamics study

Witkowska Agnieszka, Rybicki Jaroslaw, Bosko Jaroslaw, Feliziani Sandro

Abstract

We report on the results of molecular dynamics (MD) simulations of the formation of metallic granules in totally reduced lead-, bismuth- and antimony-silicate glasses of composition xMe(1-x)SiO2, Me=Pb, Pi Sb, x=0.25, 0.5. The simulations were performed in the NVE ensemble, with two-body Born-Mayer-Huggins interaction potential. For all the glasses considered a strong tendency of heavy metal atoms to agglomerate was observed. In this contribution we compare the distributions of the sizes of Pb, Bi and Sb granules and their packing.
