· JVASP-39443· OsRu3

OsRu3 is an intermetallic ceramic compound combining osmium and ruthenium, representing a refractory metal ceramic from the platinum group family. This material is primarily of research interest, investigated for extreme-temperature structural applications where conventional superalloys and ceramics reach their limits, particularly in aerospace propulsion and hypersonic environments. Its notable characteristics include exceptional hardness, chemical inertness, and thermal stability, though brittleness and cost remain significant barriers to widespread commercial adoption compared to nickel-based superalloys or conventional oxide ceramics.
