Mg4 Co2 Sb2 O12

Mg₄Co₂Sb₂O₁₂ is an experimental oxide semiconductor compound combining magnesium, cobalt, and antimony in a mixed-metal oxide framework, belonging to the broader class of complex oxides and spinel-related structures. This material is primarily of research interest for thermoelectric and magnetoelectric applications, where multivalent transition metals (cobalt) and heavy p-block elements (antimony) are explored to engineer band gaps, carrier mobility, and thermal transport properties. While not yet commercialized at scale, compounds in this family are investigated as alternatives to established thermoelectric materials (bismuth tellurides, skutterudites) and for potential use in magnetism-coupled device structures.
