· JVASP-41936· ReRu3

ReRu3 is an intermetallic ceramic compound combining rhenium and ruthenium, belonging to the family of refractory metal ceramics. This material is primarily of research and development interest for extreme-temperature structural applications where conventional superalloys reach their limits. It is explored for potential use in aerospace propulsion systems, high-temperature catalysis, and nuclear environments where its refractory properties and chemical stability at elevated temperatures offer advantages over nickel-based and titanium-based alternatives.
