摘要

利用熔淬技术合成了 As2Se3-Ag2Te-GeTe 卤化物合金。通过目视分析和 XRD 分析，证明了所获得合金的状态（玻璃、结晶、玻璃+结晶），并确定了体系中的玻璃形成区域。测定了一些样品的热特性--玻璃化温度（Tg）、结晶温度（Tcr）和熔化温度（Tm）。测量了基本的物理化学参数，如密度（d）和维氏显微硬度（HV）。计算了密实度（C）以及一些热力学特性，如弹性模量（E）、体积（Vh）和微空隙形成能（Eh），并研究了成分对这些特性的影响。碲化银的加入导致 Tg 值和 HV 值下降，d 值和 Vh 值上升。在一些合金中没有检测到结晶或熔化的热化学效应。所得结果与类似系统的现有文献数据一致。

Glass Formation and Properties of Multicomponent Glasses of the As2Se3-Ag2Te-GeTe System

Chalcogenide alloys of As2Se3-Ag2Te-GeTe were synthesized using the melt-quenching technique. By the visual and XRD analyses, the state of obtaining alloys was proven (glass, crystalline, glass + crystalline), and the glass formation region in the system was established. The thermal characteristics of some samples were determined—temperatures of glass transition (Tg); crystallization (Tcr); and melting (Tm). The basic physicochemical parameters, such as density (d) and Vickers microhardness (HV), were measured. Compactness (C), as well as some thermomechanical characteristics, such as module of elasticity (E), volume (Vh), and formation energy (Eh) of micro-voids, were calculated, and the influence of the composition on these characteristics was investigated. The addition of silver telluride resulted in a decrease in Tg and HV values and an increase in d and Vh values. No thermochemical effects of crystallization or melting were detected in some of the alloys. The obtained results were in agreement with the available literature data for similar systems.
