摘要：
The processes of glass-transition and crystallization of chalcogenide glass As40Se30Te30 with 5 at.% silver were analyzed using differential scanning calorimetry. The values of glass-transition temperatures and activation energy were determined. Two crystallization processes were also detected and three-dimensional growth. Using non-isoconversional models the activation energies for both processes amounted to 112(2) kJ/mol and 97(2) kJ/mol. Isoconversional models were used to track changes in activation energy. The presence of Te significantly affects the thermal parameters as well as the structure of the glass while the presence of Ag does not significantly change the degree of connectivity of the As40Se30Te30 glass matrix.
