metal

· JVASP-18207· ZrCoSb

ZrCoSb is an intermetallic compound combining zirconium, cobalt, and antimony, belonging to the half-Heusler alloy family. This material is primarily investigated in thermoelectric applications where it shows promise for solid-state heat-to-electricity conversion, particularly for mid-temperature power generation and waste heat recovery. ZrCoSb is notable as a research compound offering the potential for improved thermoelectric efficiency and thermal stability compared to conventional semiconductor thermoelectrics, though it remains largely in the development phase for commercial deployment.
