Effects of Content of Network-Modifying Ion and Network Structure of Sodium Silicate Glasses by Molecular Dynamics Simulation

Abstract

Network structure of sodium silicate glasses was investigated by molecular dynamics simulation. The simulations were performed that determined using the first-principles calculation. Variation of SiO₄ units and bond angles for alkali content were consistent with experimental results. It was also suggested that sodium ion and calcium ion give different effect to glass structure each other.
