Mg3Sb2 is an intermetallic semiconductor compound belonging to the magnesium-antimony family, with a zinc-blende-derived crystal structure. This material is primarily investigated for thermoelectric applications where it can convert waste heat to electrical current, and for potential use in optoelectronic devices; it remains largely a research compound rather than a commodity material, but is notable within the thermoelectric community as a candidate for mid-temperature power generation and as a platform for studying narrow-bandgap semiconductors in the Mg-Sb system.
