Sr1 Mg2 Sb2

Sr₁Mg₂Sb₂ is an intermetallic semiconductor compound belonging to the Zintl phase family, combining alkaline earth metals (strontium, magnesium) with a pnictogen (antimony). This material is primarily of research interest for thermoelectric applications, where the combination of moderate stiffness with potentially favorable electronic and phonon transport properties makes it a candidate for solid-state heat-to-electricity conversion, particularly in mid-temperature waste heat recovery systems where performance and cost-effectiveness must be balanced against more established thermoelectric materials.
