Neodymium (Nd): Essential for NdFeB Magnetic Materials, Key Additive in Specialty Alloys (Flints, Nodulizers)
Neodymium is a reactive gray metal with a density of 6.8 g/cm³ (tetragonal crystal), melting point of 1024°C, and boiling point of 3100°C. It is one of the most reactive rare earth metals, exhibiting paramagnetism. In air, it quickly tarnishes, forming oxides. It reacts slowly in cold water and rapidly in hot water.

About Neodymium
After separating neodymium from other rare earth elements via ion exchange or solvent extraction, metallic neodymium can be prepared through metallothermic reduction. Unlike calcium thermal reduction of rare earth chlorides, lithium thermal reduction occurs in the vapor phase.
The lithium thermal reduction reactor consists of two heating zones, with both reduction and distillation taking place in the same equipment. Anhydrous neodymium chloride (NdCl₃) is placed in the upper titanium crucible (also serving as the NdCl₃ distillation chamber), while the reducing agent, lithium metal, is placed in the lower crucible. The stainless steel reaction vessel is evacuated to 7 Pa before heating begins.
When the temperature reaches 1000°C, it is maintained for a set duration to ensure thorough reaction between NdCl₃ vapor and lithium vapor. The reduced neodymium metal solid particles collect in the lower crucible. After reduction, only the lower crucible is heated to distill LiCl into the upper crucible. The entire reduction process typically takes about 10 hours.
To obtain high-purity neodymium metal, 99.97% ultra-pure lithium is used as the reducing agent, along with twice-distilled anhydrous NdCl₃.
