摘要

采用差示扫描量热仪(DSC)研究了非等温条件下不同升温速率(5、10、15和20 K/min)下Se80In10Pb10硫系玻璃的结晶动力学。采用Kissinger-Akahira-Sunose、Flynn-Wall-Ozawa、Tang和Straink四种等转换方法测定了非等温模式下结晶温度(Tα)、结晶活化能(Eα)、Avrami指数(nα)等动力学参数。Se80In10Pb10从非晶到晶相的转变被认为是一个单步反应机制。

Study of Crystallization Process in Se 80 In 10 Pb 10 by Iso-Conversional Methods

The crystallization kinetics of Se80In10Pb10 chalcogenide glass is studied using differential scanning calorimeter (DSC) at different heating rates (5, 10, 15 and 20 K/min) under non-isothermal conditions. Four iso-conversional methods (Kissinger-Akahira-Sunose, Flynn-Wall-Ozawa, Tang and Straink) were used to determine various kinetic parameters: crystallization temperature (Tα), activation energy of crystallization (Eα), Avrami exponent (nα) in non-isothermal mode. The transformation from amorphous to crystalline phase in Se80In10Pb10 is considered as a single step reaction mechanism.
