· JVASP-38745· OsAu3

OsAu3 is an intermetallic compound combining osmium and gold in a 1:3 atomic ratio, belonging to the precious metal alloy family. This material is primarily of research interest rather than established industrial production, valued for its extreme density and potential high-temperature stability; it represents exploration into ultra-dense metallic systems for specialized applications where weight concentration and chemical inertness are paramount.
