2.5.2.4. Mechanical properties
Kumar et al. [59] studied the mechanical properties of TeO2-PbO-ZnF2 glasses, shown in
table (2.8).
Table (2.8): Mechanical properties of glasses (mol. %) A: 68TeO2-12PbO-20ZnF2, B:
59TeO2-11PbO-30ZnF2, C: 50TeO2-10PbO-40ZnF2, and D: 46TeO2-9PbO-45ZnF2 [59].
It can be seen, as the ZnF2 content was increased, and PbO decreased, the elastic
coefficients of the glass increased. This was thought to be due to depolymerisation of the
network with increasing PbO content, which the authors believe had a stronger effect
than ZnF2 [59].
