· KPt2Se3

KPt2Se3 is an intermetallic compound combining potassium, platinum, and selenium, belonging to the family of ternary metal selenides. This material is primarily of research and theoretical interest rather than established commercial use, investigated for its electronic and structural properties within materials science and solid-state chemistry. Compounds in this class are explored for potential applications in thermoelectrics, catalysis, and advanced electronic devices, where the combination of noble metal (Pt) with chalcogenide chemistry offers tunable band structure and chemical reactivity.
