Abstract
Bulk modulus (K-bc) and Poisson's ratio (sigma(cal)) for 25 glass compositions of the following five tellurite glass series TeO2 - WO3 - PbO, TeO2 - V2O5 - Bi2O3, TeO2 - WO3 - K2O, TeO2-Nb2O5-ZnO and TeO2-Nb2O5-ZnO-Er2O3 have been evaluated using bond compression model. Structural parameters like: number of bonds per unit volume, average stretching force constant, ratio of calculated bulk modulus to experimental bulk modulus (K-bc/K-e), atomic ring size of the glass network "ring diameter" and average crosslink density have been evaluated.
