· Sm3(Sb7Te12)2

Sm₃(Sb₇Te₁₂)₂ is a rare-earth chalcogenide ceramic compound combining samarium with antimony and tellurium in a layered structure. This material belongs to the family of complex chalcogenides under active research for thermoelectric and solid-state energy conversion applications, where the intricate crystal structure is designed to scatter phonons while maintaining electrical conductivity. Engineers consider such materials as candidates for waste heat recovery systems and specialized power generation in extreme temperature environments where conventional thermoelectrics show limitations.
