Crystallization kinetics of Si15Te85 and Si20Te80 chalcogenide glasses

Non-isothermal crystallization kinetic study on Ga15Se85−xAgx chalcogenide glasses by using differential scanning calorimetry

“…The activation energy of crystallization can also be obtained from the variation of the onset crystallization temperature T c with heating rate by using Ozawa's Eq. (23). Fig.…”

“…Under this conditions, the Avrami exponent (n) and the effective activation energy (E c ) should be constant during the transformation process. Several studies of crystallization kinetics in binary and ternary chalcogenide glasses by non-isothermal DSC methods have been widely discussed in the literature [15][16][17][18][19][20][21][22][23][24][25][26][27]. For example, Mehta et al [20] have studied a comparative analysis of thermal crystallization in Cu-Ti and Cu-Zr metallic glasses.…”

“…Elabbar et al [21] and Srivastava et al [22] have studied the crystallization kinetics of Pb-Se and Se-Te-Zn glasses by using DSC, respectively. The work on crystallization kinetics of Si-Te chalcogenide glasses by Zhang et al [23], the studies of the glass transition in amorphous Se using DSC by Abu-Sehly et al [24], thermal stability and crystallization kinetics of As-Ge-Se-Sb glasses by Dahshan [25], studies of thermal properties of chalcogenide glasses in the GeSe 2 -As 2 Se 3 -CdSe system by Zhao et al [26] and kinetics study of Se-Te-Pb using non-isothermal crystallization by Khan et al [27] are also worth mentioning.…”

Kinetics of non-isothermal crystallization of ternary Se80Te20−xZnx glasses

“…In the present work, investigations on thermal properties and the crystallization kinetics of the specially designed Se 80 Te 20−x Zn x glasses system were carried out by means of non-isothermal DSC measurement. Several workers [7][8][9][10] have reported the study of kinetics of crystallization in binary and ternary chalcogenide glasses by using non-isothermal means. In our earlier published work [11][12] on non-isothermal crystallization kinetics, we have doped Pb and Cu in Se-Te system.…”
