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.
