Approach to dissociation energy and elastic properties of vanadate and V2O5-contained glasses from single bond strength: Part I

摘要: Abstract A systematic study has been carried out to understand changes in the structure and predict composition dependence of elastic properties a large number vanadate V2O5-contained tellurite, borate phosphate glass systems. Both dissociation energy per unit volume packing density were estimated from energies factors oxide constituents. Values theoretical moduli Poisson's ratio calculated on basis Makishima–Mackenzie's theory compared with corresponding experimental values. The results reveal that, although data appear be predictable densities, majority samples have values much greater than ones. disagreement between was discussed terms basic structural units that constituting network. evaluated average single bond strength V–O P–O bonds, for first time. very good agreement theoretically experimentally measured achieved investigated samples.
