· JVASP-35285· YSi2Ru3

YSi2Ru3 is an intermetallic ceramic compound combining yttrium, silicon, and ruthenium, representing a specialized class of high-temperature ceramic materials. This is a research-stage compound primarily of interest for extreme-temperature applications where conventional ceramics or superalloys reach their performance limits. The material belongs to the family of rare-earth transition metal silicides, which are being investigated for potential use in next-generation aerospace propulsion systems and ultra-high-temperature structural applications where thermal stability, oxidation resistance, and mechanical retention at elevated temperatures are critical.
