Abstract

We have prepared extrapure Ga₁₅Ge₁₀Te_75–xI_x (x = 0–6 at %) glasses with a concentration of 31 impurity elements no higher than 0.2 ppm and studied the effect of iodine on the characteristic temperatures, crystallization resistance, thermal expansion, and density of the glasses. The results have been interpreted in terms of the structural connectivity approach. A technique has been proposed for dynamic dilatometry data processing with the aim of determining the linear thermal expansion coefficient (LTEC) as a function of temperature. The LTEC of the Ga₁₅Ge₁₀Te_75–xI_x glasses has been determined as a function of temperature in the range from 293 to 412 K.

Ga15Ge10Te75-xIx体系外渗玻璃的热性能

制备了31种杂质元素浓度不高于0.2 ppm的Ga15Ge10Te75-xIx （x = 0-6 at %）玻璃，研究了碘对玻璃的特征温度、结晶电阻、热膨胀和密度的影响。研究结果用结构连通性方法进行了解释。提出了一种动态膨胀数据处理技术，其目的是确定线性热膨胀系数（LTEC）作为温度的函数。测定了ga15ge10te75 - 19玻璃的LTEC随温度在293 ~ 412 K范围内的变化规律。
