Calorimetric studies on $Se_{0.68}Ge_{0.22}M_{0.10}(M=Cd,In,Pb)$ chalcogenide glasses

Özet

Differential scanning calorimetry (DSC) is performed at different heating rates under non-isothermal conditions to calculate the activation energy of crystallization $E_c$ for chalcogenide glasses $Se_{0.68}Ge_{0.22}M_{0.10}(M=Cd,In,Pb)$ using the well known Kissinger's relation, Matusita-Sakka theory and the method of Augis-Bennett. The overall mean bond energy <E> of these glassy alloys has been evaluated using theory of Tichy and Ticha. A good correlation has been found between $E_c$ and <E>. This indicates that the overall mean bond energy plays an important role in the thermal crystallization of chalcogenide glasses. using the well known Kissinger's relation, Matusita-Sakka theory and the method of Augis-Bennett.
