摘要

摘要 通过差热分析 (DTA)、粉末 X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 对采用特殊技术合成的尽可能接近平衡状态的 GeTe-Bi2Te3-Te 系统合金进行了表征。构建了平衡固相图、液面投影、选定的多热段和相图的 300-K 等温段。确定了各相的主要结晶场、不变平衡和单变量平衡的类型和坐标。以 GeTe-Bi2Te3 边界体系的共晶点和共晶点为起点的曲线上的单变量平衡在某些过渡点发生了转变。在浓度三角形的碲角附近发现了一连串不变的过渡反应,这是碲化物相和元素碲两相混合物联合结晶的特征。

GeTe–Bi2Te3–Te System

Abstract

Alloys of the GeTe–Bi2Te3–Te system synthesized by a special technique in a state as close to equilibrium as possible, have been characterized by differential thermal analysis (DTA), powder X-ray diffraction (XRD), and scanning electron microscopy (SEM). An equilibrium solid phase diagram, the liquidus surface projection, selected polythermal sections, and the 300-K isothermal section of the phase diagram have been constructed. The primary crystallization fields of phases, types and coordinates of invariant and monovariant equilibria have been determined. Monovariant equilibria on curves originating from the peritectic points and eutectic point of the GeTe–Bi2Te3 boundary system undergo transformations at certain transition points. A cascade of invariant transition reactions has been identified near the tellurium corner of the concentration triangle, characterizing the joint crystallization of two-phase mixtures of telluride phases and elemental tellurium.
