Th2FeSe5

Th2FeSe5 is a ternary intermetallic compound combining thorium, iron, and selenium, belonging to the rare earth and actinide metal chemistry family. This is primarily a research-phase material studied for its electronic and thermal properties rather than an established industrial material. Interest in thorium-based selenides stems from potential applications in thermoelectric devices and solid-state electronics where the combination of heavy elements and mixed valence chemistry can produce favorable carrier behavior, though practical deployment remains limited by thorium's radioactive nature and handling constraints.
