· JVASP-29355· Ta2Te3

Ta₂Te₃ is a tantalum telluride compound belonging to the ceramic/intermetallic class, combining a refractory transition metal with a chalcogenide. This material is primarily of research interest rather than established in high-volume production, with potential applications in semiconducting and thermoelectric device families where the combination of tantalum's chemical stability and tellurium's electronic properties offers selective advantages for niche high-temperature or corrosive-environment applications.
