· JVASP-69353· Ba2MgSb

Ba2MgSb is an intermetallic ceramic compound combining barium, magnesium, and antimony elements, representing a rare-earth-free material within the Heusler alloy family. This material is primarily of research interest for thermoelectric applications, where its crystal structure and electronic properties are being evaluated as a candidate for solid-state heat-to-electricity conversion in mid-range temperature regimes. Unlike conventional thermoelectric materials that rely on lead telluride or bismuth telluride, Ba2MgSb offers potential advantages in material abundance and environmental compatibility, though it remains an experimental compound with limited commercial deployment.
