Abstract
The interaction in the Sb2Te3–InSe system was studied and the T–x phase diagram was constructed by integrated methods of physicochemical analysis (differential thermal, X-ray powder diffraction, and microstructural analyses) and also by microhardness and density measurements. It was found that the Sb2Se3–InSe system is a quasi-binary section of the ternary reciprocal system Sb,In||Se,Te. In the Sb2Te3–InSe system, compounds InSb2SeTe3 and In3Sb2Se3Te3 form, which incongruently melt at 525 and 600°C, respectively. It was found that the regions of solid solutions based on Sb2Te3 and InSe extend to 3 and 2 mol %, respectively. The compounds Sb2Se3 and InSe form a eutectic with the coordinates 20 mol % InSe and 510°C. The temperature dependences of the electrical conductivity and thermal emf of the solid solutions (Sb2Te3)1 – x(InSe)x (x = 0.01, 0.02, and 0.03).

摘要
在SB的相互作用2碲3 -InSe系统进行了研究和T-X是通过物理化学分析的集成方法(差热,X射线粉末衍射,和微观结构分析)以及通过微硬度和密度测量构造相图。发现Sb 2 Se 3 -InSe系统是三元倒数系统Sb,In || Se,Te的准二元截面。在Sb 2 Te 3 -InSe系统中,化合物InSb 2 SeTe 3和In 3 Sb 2 Se 3 Te 3分别在525和600°C融化的形式。发现基于Sb 2 Te 3和InSe的固溶体区域分别扩展至3和2mol%。化合物Sb 2 Se 3和InSe形成具有20 mol%InSe和510℃的坐标的低共熔物。固溶体(Sb 2 Te 3)1 – x(InSe)x(x = 0.01、0.02和0.03)的电导率和热电动势的温度依赖性。
