Effect of zinc on the physical properties of borate glasses

► Theoretical analysis of the elastic properties of ZnO-Na2O-Al2O3-B2O3. ► Theoretical bulk modulus Kbc increases with the increase of ZnO mol% content. ► Dimensionality of glass network is reduction with increase of ZnO mol% content. ► Dissociation energy increases with increase in the number of network bond nb. ► Calculated elastic moduli were in good agreement with those obtained experimentally.
