Os1 Au3

Os1Au3 is an intermetallic compound combining osmium and gold in a 1:3 atomic ratio, representing a research-phase material in the precious metal alloy family. While not yet established in mainstream industrial production, this compound belongs to the class of noble metal intermetallics being investigated for high-temperature structural applications, catalytic systems, and specialized electronic devices where the combined properties of osmium (high density, refractory character) and gold (chemical inertness, conductivity) may offer advantages over conventional alloys. Engineers would consider this material only in specialized contexts requiring extreme chemical stability or unique electronic/catalytic behavior, recognizing it remains primarily in the experimental domain.
