· JVASP-38994· Zr2CoOs

Zr2CoOs is an intermetallic compound combining zirconium, cobalt, and osmium, representing a research-phase material in the family of refractory intermetallics and high-entropy alloy precursors. This material is primarily of interest in fundamental materials science and experimental engineering contexts rather than established industrial production, with potential applications in extreme-temperature structural applications, aerospace component research, and advanced catalytic systems where corrosion resistance and thermal stability are critical. The combination of a heavy refractory metal (Os) with transition metals (Zr, Co) suggests investigation into materials for high-temperature oxidation resistance, making it notable as a candidate for next-generation turbine materials or protective coatings in high-entropy alloy research programs.
