- Title
Molecular dynamics simulation of sodium germanate glasses and the germanate anomaly.

- Abstract
Molecular dynamics (MD) calculations for sodium germanate glasses were carried out using a simple two-body interaction potential model to investigate structural changes and the germanate anomaly. The simulation results, including changes in the density, coordination number of Ge atoms around an O atom and average bond length between O and Ge atoms with increasing alkali content, show good agreement with experimental results. These results indicate that MD simulation for sodium germanate glasses using a simple two-body interaction model can reproduce the structures of sodium germanate glasses.
