2. Literature review; MDO 58
Table (2.7): Characteristic temperatures, glass transition, Tg, onset of crystallisation, Tx,
and peak crystallisation, Tc, with glass density (ρ), and electric absorption edge (λc) for
TeO2-ZnO-ZnF2 glasses [30].
2.5.2.3. Optical properties
Adams [56] measured the IR-spectra of glasses in the system TeO2-PbO-ZnF2 as shown
in fig. (2.14). Trace (a) 15.17 mol. % ZnF2, (b) 28.92 mol. % ZnF2, (c) 40.91 mol. %
ZnF2, and (d) 51.81 mol. % ZnF2.
