Er3Ni7B2
metal· JVASP-22857· Er3Ni7B2
Er₃Ni₇B₂ is a rare-earth nickel boride intermetallic compound combining erbium, nickel, and boron in a crystalline structure. This material belongs to the family of rare-earth transition metal borides, which are primarily of research interest for their potential in high-temperature applications and magnetic applications due to the rare-earth constituent. While not yet widely established in production engineering, materials in this class are investigated for advanced aerospace, energy conversion, and specialized magnetic device applications where extreme thermal stability or rare-earth magnetism could provide advantages over conventional superalloys or permanent magnets.
