ceramic

· JVASP-143506· SbTeIr

SbTeIr is a ternary ceramic compound composed of antimony, tellurium, and iridium. This is an experimental material primarily of research interest in thermoelectric and advanced functional ceramic applications, where the combination of heavy elements and transition metal character offers potential for phonon scattering and electronic tuning. The material's position in the antimony-tellurium-iridium phase space suggests exploration for high-temperature stability, wear resistance, or specialized electronic/thermal transport properties where conventional ceramics prove inadequate.
