· Ca2 Co1 W1

Ca₂CoW is an intermetallic compound combining calcium, cobalt, and tungsten in a 2:1:1 ratio, classified as a semiconductor material. This ternary compound is primarily of research interest for potential applications in thermoelectric energy conversion and advanced electronic devices, where the combination of transition metals (Co, W) with an alkaline earth element (Ca) can create favorable electronic band structures. While not yet widely deployed in commercial applications, materials in this family are investigated for their potential to convert waste heat to electricity or serve as semiconducting phases in composite systems, positioning them as candidates for next-generation energy and electronics technologies.
