· JVASP-10152· K3SiTe3

K₃SiTe₃ is an inorganic ceramic compound combining potassium, silicon, and tellurium elements. This is a specialized research material within the silicate-telluride family, currently in early-stage investigation rather than established industrial production; it is studied for potential applications in thermoelectric devices and solid-state materials where the combination of moderate stiffness and density could enable novel thermal or electrical management functions.
