· JVASP-15504· ErSi2Ru2

ErSi2Ru2 is an intermetallic ceramic compound combining erbium, silicon, and ruthenium. This material represents a research-phase silicide system that leverages ruthenium's refractory properties and chemical stability, with potential applications in extreme-temperature environments where conventional ceramics reach their limits. The erbium addition may enhance specific mechanical or thermal properties, making this compound of interest for advanced aerospace and high-temperature structural applications, though it remains primarily in experimental development stages rather than established industrial production.
