· JVASP-14179· Er2Mg

Er2Mg is an intermetallic ceramic compound combining erbium (a rare-earth element) with magnesium, belonging to the family of rare-earth magnesium ceramics. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural composites, thermal management systems, and advanced aerospace components where rare-earth strengthening mechanisms offer benefits over conventional ceramics. The erbium-magnesium system is studied for its potential to combine magnesium's lightweight properties with erbium's rare-earth contribution to high-temperature stability and oxidation resistance, though it remains largely in experimental phases compared to more mature ceramic systems.
