· JVASP-16254· Er2AlSi2

Er₂AlSi₂ is an intermetallic compound combining erbium, aluminum, and silicon, belonging to the rare-earth metal silicide family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural components and advanced aerospace systems where rare-earth strengthening and thermal stability are desired. The erbium content provides enhanced hardness and creep resistance compared to conventional aluminum silicides, making it a candidate material for next-generation turbine engines and thermal barrier systems operating in extreme environments.
