摘要

In this paper, thermo-physical parameters of the samples under investigation are deduced using theoretical models and a comparison is made with experimental results. The amorphous samples (Se $_{\text{80}}$ $_{80}$ Te $_{\text{20}}$ $_{20}$ ) $_{\text{94-x}}$ $_{94-x}$ Ge $_{\text{6}}$ $_{6}$ Sb $_{{\mathrm{\text{x}}}}$ $_{x}$ (x = 1, 2, 4 and 8) are primed via melt-quenching procedure. The thermal behaviour is obtained by reheating the prepared samples in differential scanning calorimetric experiment under non-isothermal settings at four scanning rates starting from 5 $^o$ $^{o}$ Cmin $^{-1}$ $^{- 1}$ in the steps of five up to 20 $^o$ $^{o}$ Cmin $^{-1}$ $^{- 1}$ . The specific temperatures $T_{\mathrm{g}}$ $T_{g}$ , $T_{\mathrm{c}}$ $T_{c}$ , $T_{\mathrm{p}}$ $T_{p}$ and $T_{\mathrm{m}}$ $T_{m}$ are considered to determine thermo-physical parameters and thermal stability and glass-forming ability is also interpreted. Thermo-physical parameters such as average coordination number, floppy modes, lone-pair electrons, mean bond energy, heat of atomization and electronegativity are deduced theoretically, and their interdependence as well as compositional dependence is reported and discussed.
