· JVASP-29721· In2Te5

In₂Te₅ is an indium telluride ceramic compound belonging to the III-VI semiconductor family, characterized by a layered crystal structure. This material is primarily of research and emerging technology interest rather than a mature industrial ceramic, with potential applications in thermoelectric devices, infrared optics, and semiconductor research where its narrow bandgap and thermal properties may offer advantages over conventional alternatives.
