· KCu4Se3

KCu₄Se₃ is an intermetallic compound combining potassium, copper, and selenium—a research-phase material that belongs to the family of ternary metal chalcogenides. While not yet established in mainstream engineering, compounds in this chemical family are of interest to materials scientists for potential applications in thermoelectric devices and solid-state electronics, where the combination of metallic and semiconducting character can be tuned through composition. Engineers would consider this material primarily in advanced materials research contexts rather than current production applications.
