· JVASP-15806· CaZn2Sb2

CaZn2Sb2 is an intermetallic ceramic compound belonging to the Zintl phase family, characterized by calcium, zinc, and antimony in a defined stoichiometric ratio. This material is primarily of research interest for thermoelectric applications and solid-state electronic devices, where its crystal structure and electronic properties are being evaluated for energy conversion and semiconductor functionality. While not yet widely established in high-volume industrial production, compounds in this family are investigated as potential alternatives to conventional thermoelectrics and as components in advanced materials systems where the combination of metallic and semi-metallic bonding character offers tunable electrical and thermal transport properties.
