Korea Institute of Materials Science Develops Core Technology for High-Performance Permanent Magnets Without Heavy Rare Earths
Published2026.10.23 08:53
고가의 중희토류를 사용하지 않고도 고성능 영구자석을 제조할 수 있는 일괄 핵심기술을 확보한 것이다.
이들 원소는 자석의 보자력을 높이는 데 필요하지만 가격이 높고 공급이 특정 국가에 집중돼 안정적인 조달이 어렵다는 문제가 있다.
연구팀은 초미세분말 합성 기술을 통해 중희토류 없이도 자석 성능을 유지할 수 있는 공정 경로를 구현했다고 설명했다.
연구원 측은 핵심 소재의 국산화 가능성을 높이고 공급망 리스크를 줄이는 데 기여할 것으로 내다봤다.
연구 관련 문의는 한국재료연구원 나노재료연구본부 김수민 선임연구원(055-280-3622)으로 하면 된다.
