연구실 소개
이경우 교수 연구실은 고순도 마그네슘 금속의 친환경적 제련 기술 개발을 핵심으로 하며, 마그네사이트, 석회석, 폐기물 자원 등 다양한 산화마그네슘 자원을 원료로 사용하는 전기화학적 분해 기반의 마그네슘 생산 공정을 연구하고 있습니다. 특히, 불화염류 및 산화물 전해질을 활용한 고온 전기분해 기술을 통해 높은 전류 효율과 순도를 확보하고 있으며, 철산화물의 전기분해를 통한 탄소 배출 감소 기술도 동시에 개발하고 있습니다. 이는 철강 및 첨단 소재 분야에서의 탄소중립 기술 기반 마련에 기여할 잠재력을 지닙니다.

Use of various MgO resources for high-purity Mg metal production through molten salt electrolysis and vacuum distillationHyeong-Jun Jeoung, Tae-Hyuk Lee, Youngjae Kim, Jin‐Young Lee, Young Min Kim, Toru H. Okabe, Kyung‐Woo Yi, Jungshin Kang
SJR Q1Journal of Magnesium and AlloysOA
A green and effective electrolytic process was developed to produce high-purity Mg metal using primary and secondary resources containing MgO as a feedstock. The electrolysis of various MgO resources was conducted using a Cu cathode in MgF2 – LiF – KCl molten salt at 1043 K by applying an average current of 1.44 A for 12.5 h. The electrolysis of calcined North Korean magnesite and seawater MgO clinker yielded Mg alloys of MgCu2 and (Cu) phases with current efficiencies of 89.6–92.4%. The electro
