ABSTRACT = {The study is dedicated to the investigation of thermo-physical characteristics of Se<sub>95</sub>Te<sub>5</sub> 
chalcogenide glassy semiconductor during its glass formation and crystallization 
processes, employing various scanning rates of 5, 10, 15 and 20 K/min in non-isothermal 
modes through DSC measurement. Analysis of the structural relaxation kinetics involves 
the Kissinger’s, Augis and Bennett's, as well as Matusita’s approaches. Experimental data 
yield contains the determination of crucial parameters such as glass transition (T<sub>g</sub>), 
crystallization(T<sub>c</sub>), and melting temperatures alongside factors like reduced temperature of 
glass transition (T<sub>rg</sub>), Hruby’s parameter (K<sub>gl</sub>), fragility index (F<sub>i</sub>), Avrami exponents (n, 
m), glass transition (140.24 kJ/mol) and crystallization (Ec = 95.11 kJ/mol) energies, 
respectively. The results confirm that Se<sub>95</sub>Te<sub>5</sub> chalcogenide system as an efficient glass 
former. Matusita’s method reveals that the crystallization mechanism (n = 2.51, m = 1.9) 
corresponds to volumetric nucleation with two-dimensional growth. },
