· JVASP-55256· BaAg2Te2

BaAg₂Te₂ is an intermetallic compound combining barium, silver, and tellurium in a layered crystal structure. This material is primarily of research interest rather than established industrial production, belonging to the family of mixed-metal chalcogenides being investigated for thermoelectric and electronic applications. Its potential lies in advanced energy conversion devices and semiconducting systems where the combination of heavy atoms (Ba, Te) and good electronic carriers (Ag) can be engineered to reduce thermal conductivity while maintaining electrical transport.
