Detailed study about the thermal behavior and kinetics characterization of an oxyfluoride tellurite glass
Source abstract
Abstract
Abstract As a continuation of the earlier work (synthesis and optical properties of new fluoro-tellurite glass within (TeO2 ZnO LiF Nb2O5 NaF) system), the thermal behavior and kinetics characterization of the oxyfluoride tellurite system have been achieved as a function of growing the mol% of NaF. The differential scanning calorimetry (DSC) technique at various heating rates under the non-isochronal conditions was used to identify the characteristic temperatures like the glass transition (Tg), the softening (Ts), the crystallization (Tc), the liquidus (TL), and the melting (Tm) of the system. The glass stability and glass forming ability (GFA) parameters were determined based on these characteristic temperatures. The activation energies of both the glass transition (Eg) and crystallization (Ec) have been computed by different methods. The Avrami kinetic constant (n) has been determined by more than a method to identify the crystallization succession.
