The transition to a hydrogen-based economy necessitates the development of safe, cost-effective hydrogen storage media at an industrial scale. equiatomic intermetallic titanium–iron (TiFe) alloy is prime candidate for stationary applications due its high volumetric density, nontoxicity, and safety attributes. However, conventional synthesis TiFe relies on purity titanium iron metal feedstocks, which must first be extracted from their respective ores before being alloyed in ratio. This...
The Republic of Korea is one the largest consumers and a leading exporter electronics, medical appliances, heavy light vehicles. Rare-earth (RE)-based magnets are indispensable for these technologies, totally dependent on imports compounds or composites REEs, as country lacks natural resources. Effect rare earth supply chain significantly affects Korea’s transition towards green economy. This study investigates approach to developing secure REE via recycling materialization process known...
During the liquid metal extraction reaction between a Nd-Dy-Fe-B magnet and Mg, Nd rapidly diffuses out of magnet, whereas Dy is not extracted due to with matrix formation Dy2Fe17 phase. In addition, theDy2O3 phase exists at grain boundaries. Until now, only effect Dy2O3 on has been reported. this study, from was investigated in Mg. The during Mg (RE2Fe14B) first examined using thermodynamical approach confirmed by microstructural analysis. It observed that dominated decomposition 3 h 24 h,...
Liquid metal extraction (LME) process results in 100% neodymium (Nd) but the highest efficiency reported for Dysprosium (Dy) so far is 74%.Oxidation of Dy major limiting factor incomplete extraction.In order to enhance and further investigate factors extraction, experiments were carried out on six different particle sizes under 200 μm, 200-300 300-700 700-1000 1000-2000 μm over 2000 at 900℃ with magnesium-to-magnet scrap ratio 15:1 6, 24 48 hours, respectively.This research identified 2 Fe...
Phase evolution During extraction anD recovery of Pure nd from magnetLiquid Metal process using molten Mg was carried out to obtain Nd-Mg alloys Nd based permanent magnets at 900 o C for 24 h.with a magnet magnesium mass ratio 1:10.Nd successfully extracted into resulting in ~4 wt.% alloy.Nd recovered the obtained on difference their vapor pressures vacuum distillation.Vacuum distillation experiments were 800 under 2.67 Pa various times high purity Nd.Nd having more than 99% time 120 min and...
