ceramic

· JVASP-8199· YbCd2Sb2

YbCd₂Sb₂ is an intermetallic ceramic compound belonging to the rare-earth cadmium antimonide family, combining ytterbium with cadmium and antimony in a defined stoichiometric ratio. This material is primarily of research interest for thermoelectric and semiconducting applications, where the rare-earth element ytterbium can contribute to tunable electronic and thermal transport properties. The material family is explored for potential use in solid-state cooling, waste heat recovery, and specialty electronic devices where the interplay between metallic and semiconducting character offers advantages over conventional alternatives.
