· JVASP-15310· SmSi2Ru2

SmSi2Ru2 is an intermetallic ceramic compound combining samarium, silicon, and ruthenium, belonging to the family of rare-earth transition metal silicides. This material is primarily investigated in research contexts for high-temperature structural applications and advanced ceramics, where the combination of rare-earth and noble-metal components offers potential for thermal stability, oxidation resistance, and mechanical performance at elevated temperatures. The material represents an emerging class of compounds of interest to aerospace and materials science researchers seeking alternatives to conventional refractory ceramics and superalloys for extreme-environment applications.
