Abstract

The feasibility of using layers of metallic chromium as a switching material for a medium-temperature thermoelectric CrSi₂ is investigated. The CrSi₂/Cr samples are synthesized by the hot pressing of a fine electrolytic chromium powder with single-crystal and polycrystalline chromium disilicide, followed by high-temperature annealing. X-ray phase analysis, scanning electron microscopy, energy X-ray dispersive spectroscopy and electron backscatter diffraction showed that no secondary phases are formed both in the bulk of the thermoelectric material and at the CrSi₂–Cr interface. Therefore, Cr can be recommended as a switching material.

使用铬作为 CrSi2 开关材料的可行性

摘要

研究了使用金属铬层作为中温热电 CrSi ₂开关材料的可行性。CrSi ₂ /Cr 样品是通过将电解铬细粉与单晶和多晶二硅化铬热压，然后高温退火合成的。X 射线相分析、扫描电子显微镜、能量 X 射线色散光谱和电子背散射衍射表明，在热电材料的主体和 CrSi ₂ -Cr 界面均未形成二次相。因此，可以推荐 Cr 作为开关材料。
