“…Fluoroindate glasses are promising materials with potential applications as infrared optical materials. Since the development of these applications requires reduced intrinsic nucleation and crystal growth, the crystallization kinetics of the InF 3 -based glasses have been extensively studied in the last decade by isothermal and non-isothermal methods [25][26][27][28][29][30]11]. In a previous paper we reported a DSC, XRD and 19 F nuclear magnetic resonance (NMR) investigation of the crystallization and nucleation processes occurring in the fluoroindate glass 40InF 3 -20ZnF 2 -20SrF 2 -20BaF 2 .…”

“…This method of calculation of activation energy is referred to as VHR (Various Heating Rate) method as suggested by several research groups [37][38][39]. The Avrami exponent (order parameter) is determined at a specific temperature by the following equation as suggested by Boutarfaia et al 2002 andChristian 1971 [40, 41]:…”

In the liquid-solid phase transition analysis, it was observed that two phenomena namely crystallization and glass transition take place, whenever we cool a liquid or melt a solid. In the present endeavor, we have tried to analyze the comparative study of crystallization kinetics using comprehensive iso-conversional methods in both heating/cooling modes of quaternary Se76Te20Sn2Ge2 glassy material synthesized by a very simple and famous melt quenching technique. Differential Scanning Calorimetry (DSC) was employed for this analysis. The effect of heating, as well as cooling rates on the crystallization kinetics, was investigated. Various kinetic parameters like activation energy using the iso-conversional approach, the reaction rate constant, Avrami index, Meyer-Neldel energy, etc. have been calculated for both heating and cooling modes.

In the present work, we have prepared high yield of glassy Se 98 Cd 2 nanorods using melt-quench technique. The morphology and micro-structural analysis of as-prepared nanorods are characterized by SEM, XRD and EDX techniques. The glass transition and crystallization kinetics of glassy Se 98 Cd 2 nanorods are studied at different heating rates (5, 10, 15, 20 K/min) using differential scanning calorimetric (DSC) technique. Four isoconversional methods [Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), Tang and Straink] were used to determine the various kinetic parameters (crystallization temperature T ac , transition temperature T ag , activation energy of crystallization E ac , activation energy of glass transition E ag , order parameter n) of glass transition and crystallization process in non-isothermal mode. The monotonous decrease in activation energy E a with the crystallization fraction a confirm the complex kinetic mechanism of the glassy Se 98 Cd 2 nanorods.
