· KCo2Se2

KCo₂Se₂ is an intermetallic compound combining potassium, cobalt, and selenium in a defined stoichiometric ratio, belonging to the family of ternary metal selenides. This material is primarily of research interest rather than established commercial production, investigated for potential applications in thermoelectric devices, quantum materials studies, and solid-state chemistry due to the electronic properties arising from its layered crystal structure and transition metal content.
