· JVASP-2556· CaCd2Sb2

CaCd₂Sb₂ is a ternary intermetallic ceramic compound combining calcium, cadmium, and antimony. This material belongs to the family of Heusler alloys and related intermetallic compounds, which are primarily of research and development interest rather than established commercial materials. The compound is studied for potential applications in thermoelectric devices, semiconducting applications, and as a model system for understanding electronic and thermal transport in ternary metal systems, though practical industrial adoption remains limited due to toxicity concerns with cadmium and the challenges of processing intermetallic ceramics at scale.
