Abstract For the obtained high-purity glasses of crystallization-resistant compositions Ge0.25-yGayTe0.75-xIx (y = 0.10, 0.15, x = 0-0.06 mol fractions) by method TM-DSC heat capacity experimentally determined and glass transition characteristics studied. Based on the results of theoretical processing of calorimetric data, standard thermodynamic functions were calculated in the temperature range 0–530 K which are complemented by temperature dependences of density and coefficient of thermal expansion. These thermodynamic functions are necessary for determining the conditions of synthesis by minimizing the Gibbs energy of promising representatives of the glass-forming system Ge–Ga–Te–I and prediction of the properties of glasses including those with functional additives that determine their optical-sensory applications.

用于光学应用的 Ge0.25-Ga Te0.75-I 玻璃（y = 0.10, 0.15；x = 0 – 0.06 摩尔分数）的热力学性质

摘要 对于得到的抗结晶成分Ge0.25-yGayTe0.75-xIx（y = 0.10, 0.15, x = 0-0.06 mol分数）的高纯玻璃，通过TM-DSC方法实验测定的热容和玻璃化转变特性学习了。基于量热数据的理论处理结果，在 0-530 K 的温度范围内计算了标准热力学函数，并辅以密度和热膨胀系数的温度依赖性。这些热力学函数对于通过最小化玻璃形成系统 Ge-Ga-Te-I 的有希望代表的吉布斯能量来确定合成条件和预测玻璃的性质（包括具有决定其光学感官的功能添加剂的那些）是必要的应用程序。
