· JVASP-50854· Er2CuO4

Er₂CuO₄ is a rare-earth copper oxide ceramic compound belonging to the family of erbium-based cuprates. This material is primarily of research and theoretical interest rather than established industrial production, investigated for its potential electronic and magnetic properties in the context of high-temperature superconductor research and advanced ceramics development. Its notable position in the cuprate family makes it relevant to materials scientists exploring new compositions for electrical, magnetic, or thermal applications, though practical engineering adoption remains limited compared to better-characterized alternatives.
