Structural interpretations on tellurite glasses

Molar and mean atomic volumes have been calculated and analyzed for binary tellurite glasses doped with transition metal oxides (TMO) like MoO3 and V2 O5 Analysis of the compositional dependence of elastic properties of the bi nary tellurite glasses in terms of the bulk modules-volume and bond compres sion model relationships have been achieved. The number of bonds per unit v olume, the value of the average stretching force constant present in the bi nary glasses have been calculated in order to discuss the inter-atomic bond ing of network modifiers and network former and their correlation with the elastic property of the present noncrystalline solid. Both Debye and Einste in temperatures with the values of the mean atomic volume and number of vib rating atoms per unit volume present in the binary glasses have been calcul ated and discussed.
