· KPt2S3

KPt₂S₃ is an intermetallic compound combining potassium, platinum, and sulfur, belonging to the family of ternary metal chalcogenides. This is a research-phase material studied primarily for its electronic and structural properties rather than a commercial engineering material in widespread use. The compound is of interest in materials science for understanding metal-sulfide interactions and potential applications in catalysis, energy storage, or thermoelectric systems, though development remains at the laboratory stage.
