Abstract
In the present paper crystallization kinetics of Ge25‐xSe75Sbx(x = 12, 15, 18) chalcogenide glasses has been investigated using thermal analysis (TA) technique. Ge25‐xSe75Sbx (x = 12, 15, 18) chalcogenide glasses have been prepared by rapid quenching of melt technique. For structure characterization XRD technique has been used. Out of various TA techniques Differential Scanning Calorimetery (DSC) has been used for present study. DSC scans have been carried at different heating rates i.e. 5, 10, 15 and 20 K/min. For evaluation of activation energy of crystallization various theoretical models Kissinger, Ozawa, Augis‐Bennet and Matusita‐Sakka have been used. Activation energy of crystallization increases with increase of Sb content in Ge25‐xSe75Sbx(x = 12, 15, 18) glassy series. The value of Avrami index indicates bulk crystallization with one or two dimensional growth.
