Kinetics of non-isothermal crystallization and glass transition phenomena in Ga10Se87Pb3 and Ga10Se84Pb6 chalcogenide glasses by DSC

“…DSC is one of the important tools to study of glass transition phenomena and crystallization kinetics, which has been widely discussed in the literature [1][2][3][4][5][6][7][8][9]. Zhang et al [10] has studied the crystallization kinetics of Si 15 Te 85 and Si 20 Te 80 chalcogenide glasses, El-Raheem et al [11] has studied the crystallization kinetics determination of Pb 15 Ge 27 Se 58 chalcogenide glass by using the various heating rates method, Elabbar et al [12] has studied the crystallization kinetics study of Pb 4.3 Se 95.7 chalcogenide glass using DSC technique, Aly et al [13] has studied the effect of Te additions on the glass transition and crystallization kinetics of (Sb 15 As 30 Se 55 ) 100 − x Te x amorphous solids.…”

Glass-crystal transformations in Se80−xTe20Agx (x=0, 3, 5, 7 and 9) glasses

“…Recently, a great deal of work has been done in the field of chalcogenide glasses due to their useful applications in solid-state electronics [1][2][3], infrared optical fibers [4], semiconducting properties [5,6] and in optical recording [7].…”

Non-isothermal crystallization kinetics and mechanical properties of Al 86 Ni 6 Y 4.5 Co 2 La 1.5 metallic glass powder

“…Based on Eqs. (1) and (2), the Avrami exponent can be obtained using the non-isothermal method [15] as follows:…”

“…(3) to calculate the Avrami exponent, two fractions of crystallization X 1 and X 2 are required. Following the literature [15], X 1 and X 2 are normally chosen to be 0.3 and 0.7, respectively. The corresponding temperatures T 1 and T 2 and transformation times t 1 and t 2 for two given crystallization fractions can thus be drawn and calculated from the kinetics curves shown Table 1 The Avrami exponent n for each crystallization stage obtained from the crystallization fraction curves (Fig.…”

“…To understand the nucleation and growth mechanism for crystallization, the apparent activation energies and the Avrami exponent were determined using similar methods adopted in [11,12]. The crystallization process was analyzed using the Johnson-Mehl-Avrami (JMA) model [13][14][15].…”
