ceramic

· JVASP-99143· K3SbTe3

K3SbTe3 is a ternary chalcogenide ceramic compound composed of potassium, antimony, and tellurium. This is an experimental/research material investigated primarily for thermoelectric and solid-state energy conversion applications, where the combination of elements is selected to optimize phonon scattering and charge carrier mobility in the crystal lattice. The material belongs to a family of heavy-element semiconductors that show promise for waste heat recovery and thermal-to-electric energy conversion in the mid-range temperature window, offering potential advantages over conventional thermoelectric materials in specific operating regimes.
