    Medium- and long-range order in binary sodium-silicate glasses simulated by molecular dynamics
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 2004) Gedeon, Ondrej; Machéček, Jan; Liška, Marek
    Molecular dynamics simulations of xNa₂O(1-x)SiO₂ glasses, for x = 0, ..., 0.66, were performed. The obtained structure at the normal temperature was described in frame of Q-species, bridging and non-bridging oxygen distributions, bonding defects, and connectivity. Distributions of Q-species are compared with the "structurally ideal" model glass. In addition, simulated results are compared with the available experimental data.
