Title: | Calculation of non-isothermal crystallization parameters for the Cu15(As2Se3)85 metal-chalcogenide glass | Authors: | Kozmidis-Petrović A. Lukić-Petrović, Svetlana Štrbac, Goran |
Issue Date: | 1-Sep-2010 | Journal: | Journal of Non-Crystalline Solids | Abstract: | This work analyzes the possibility of using an alternating series development in deriving the relations allowing the determination of the parameters of non-isothermal crystallization. When this series development is applied onto the process of non-isothermal glass crystallization it suffices to take only the first term of the series. Linear fitting yields a relation from which one can determine the Avrami parameter n, dependent on the crystallization mechanism, and the activation energy. By an analogous procedure, taking the first two terms of the developed series, one obtains the Matusita equation. Both of these relations hold also when the temperature T is only somewhat higher than the initial To, and not only when T > > To. Experimental measurements by differential scanning calorimetry method and the application of the relations derived, as well as of other standard methods for calculating parameters of non-isothermal crystallization, were performed for the chalcogenide glass Cu15(As2Se3)85. © 2010 Elsevier B.V. | URI: | https://open.uns.ac.rs/handle/123456789/14905 | ISSN: | 00223093 | DOI: | 10.1016/j.jnoncrysol.2010.08.026 |
