Abstract :
Insight into the Zn structural role in a series of glasses of composition (Na2O)1−x · CaO · (ZnO)x · 2SiO2 (x = 0, 0.2, 0.6 and 1) has been obtained by density measurements, analysis of the crystals separated from the glasses, micro-Raman spectra and molecular dynamics simulations. We found that Zn acts as a weak tetrahedral network former independent of the glass Na content.
