Viscosity and crystallization kinetics of As2Se3

Structural relaxation of As2Se3 glass and viscosity of supercooled liquid

“…However, at slower cooling rate it is possible to detect a plateau corresponding to a l = (90 ± 3) · 10 À6 K À1 . These values of thermal expansion coefficient are different than reported Henderson and Ast [17] Fig. 1.…”

“…Fig. 1 combines our viscosity results, data reported by Henderson and Ast [17] and Weber and Savage [18] for practically the same temperature region. All these data can be described by the Vogel-FulcherTamman equation…”

“…The temperature dependence of the viscosity for As 2 Se 3 supercooled liquid. The points represent data summarized in Table 1 (d), data reported by Henderson and Ast [17] (h) and Weber and Savage [18] (n). The solid line is best fit of Eq.…”

Kinetics of crystal growth of Sb2S3 in (GeS2)0.3(Sb2S3)0.7 glass

“…The activation energy of crystal growth represents about 60% of the activation energy of viscous flow in (GeS 2 ) 0.3 (Sb 2 S 3 ) 0.7 supercooled melt (E g = 485 ± 8 kJ mol À1 ) [14,15]. A similar result was reported for crystallization of As 2 Se 3 in the supercooled melt of the same composition [41]. Recently, this behavior has also been found for crystallization of GeS 2 in the supercooled melt of Ge 0.38 S 0.62 composition [42].…”

Crystallization Kinetics of CaO-SiO₂(CaO/SiO₂=1)-TiO₂-10 mass%B₂O₃ Glassy Slag by Differential Thermal Analysis

“…Many researchers have proposed some methods on non-isothermal crystallization kinetics. [25][26][27][28] One of these methods is the well-known Matusita-Sakka model. Matusita and coworkers [29][30][31] emphasized that the crystallization mechanism, such as bulk crystallization or surface crystallization, should be taken into consideration for acquiring the meaningful activation energy.…”
