· JVASP-41931· IrRu3

IrRu3 is an intermetallic ceramic compound composed of iridium and ruthenium, both refractory noble metals, designed for extreme-temperature and high-corrosion environments. This material belongs to the family of platinum-group intermetallics and is primarily of research and specialized industrial interest, valued in aerospace, catalysis, and chemical processing where thermal stability, oxidation resistance, and noble-metal corrosion immunity are critical. Its exceptional density and refractory properties make it a candidate for applications requiring performance beyond conventional superalloys, though limited availability and cost restrict its use to demanding niche applications where alternatives cannot survive the operating environment.
