· JVASP-9705· ReTeS

ReTeS is a ceramic compound combining rhenium, tellurium, and sulfur, representing a transitional material class that bridges conventional ceramics and chalcogenide semiconductors. This material is primarily of research interest for its potential in high-temperature structural applications and thermoelectric energy conversion, where its combination of ceramic hardness with metallic-like thermal and electrical properties offers advantages over purely conventional ceramics. ReTeS and similar ternary chalcogenides are explored as candidates for extreme environment applications where conventional oxide ceramics reach performance limits, though industrial adoption remains limited and material behavior is still being characterized.
