The structures of amorphous zinc silicate and sodium zinc silicate have been studied using the molecular dynamics computer simulation technique. Results showed that bond lengths and coordination numbers for the individual atomic species fit within the range of results from a number of crystalline and glassy silicates. Discrete ZnO4 tetrahedra were seen to exist to a higher degree in the sodium zinc silicate system due to charge compensation from neighboring sodium atoms. Simulation results are also compared to EXAFS data of low concentrations of zinc oxide in silica and sodium silicate glasses. The local environment of oxygen in the simulated systems is also discussed.
