· JVASP-3000· BaMg2Sb2

BaMg₂Sb₂ is an intermetallic ceramic compound belonging to the family of Zintl phases—a class of materials with mixed ionic-covalent bonding that combines metallic and semiconducting characteristics. This is a research-stage material primarily investigated for thermoelectric and electronic applications where the layered crystal structure and balanced mechanical-electrical properties of Zintl phases offer potential advantages over conventional ceramics.
