UIr3

UIr3 is an intermetallic ceramic compound based on uranium and iridium, representing a refractory ceramic material designed for extreme-temperature and high-stress environments. This material belongs to the family of uranium-based intermetallics, which combine the density and nuclear properties of uranium with the hardness and oxidation resistance of iridium. While primarily a research and specialized industrial compound rather than a commodity ceramic, UIr3 is explored for applications requiring materials that can withstand severe thermal cycling, chemical aggression, and mechanical loads where conventional refractories fall short.
