Er2 Ni8 B2

Er₂Ni₈B₂ is an intermetallic compound combining erbium (a rare-earth element), nickel, and boron—a material family of interest primarily in research rather than established commercial production. This compound belongs to the rare-earth intermetallic class and is investigated for potential applications in magnetic, electronic, or thermal management systems where rare-earth elements provide functional properties; however, it remains largely experimental with limited industrial adoption compared to more common rare-earth alloys like Nd₂Fe₁₄B (neodymium magnets) or established Ni-based superalloys.
