Abstract

Magnesium has been used as parts of vehicles, case materials of notebook PC and mobile phone, and its demand has been increasing recently. Its extraction technologies were classified according to the two major reduction methods: the fused salt electrolysis and the thermal reduction method. A research on the extraction of magnesium from magnesite which has been being carried out at KIGAM was briefly introduced here. Magnesium was prepared using a fused salt electrolysis method through preparation of anhydrous magnesium chloride with lab scale experiments.

최근 국내 자동차부품 및 전자기기 산업에서 마그네슘 금속의 수요가 증가하고 있다. 마그네슘 제련은 크게 용융염전해법과 열환원법 두 가지로 대별할 수 있는데, 본 고에서는 마그네슘 금속 제련에 관하여 원료 광석인 마그네사이트로부터 무수염화마그네슘 제조를 거쳐 용융염전해법에 의한 금속 마그네슘 제조까지 실험실 규모로 전해 마그네슘을 제조한 내용을 요약 보고하였다.
