· JVASP-16093· SmSiRu

SmSiRu is an intermetallic ceramic compound combining samarium, silicon, and ruthenium, belonging to the class of ternary transition metal silicides. This material is primarily of research and developmental interest, studied for applications requiring high-temperature structural performance and oxidation resistance due to the refractory nature of ruthenium-containing silicates and the thermal stability contributions of rare-earth samarium.
