· Ca3BiSb

Ca3BiSb is an intermetallic ceramic compound composed of calcium, bismuth, and antimony, belonging to the class of ternary ceramics and intermetallic materials. This material is primarily of research interest for thermoelectric and semiconducting applications, where bismuth-containing compounds are valued for their phonon-scattering properties and potential to convert waste heat to electrical energy. Its real-world deployment remains limited; it is investigated in academic and materials research settings as a candidate for solid-state power generation and thermal management systems where conventional thermoelectrics (bismuth telluride alloys) face cost or performance constraints.
