Production Method
After separating gadolinium from other rare earths via ion exchange/solvent extraction, metallothermic reduction prepares metallic gadolinium. Unlike calcium reduction, lithium reduction occurs in gas phase. The lithium reduction reactor has two heating zones, combining reduction and distillation. Anhydrous GdCl₃ is placed in the upper titanium crucible (also serving as distillation chamber), with lithium metal in the lower crucible. The stainless steel vessel is evacuated to 7Pa before heating. At 1000°C, GdCl₃ vapor reacts with lithium vapor, depositing gadolinium particles in the lower crucible. Post-reaction, only the lower crucible is heated to distill LiCl upward. The 10-hour process requires 99.97% pure lithium and doubly distilled anhydrous GdCl₃ for high-purity gadolinium.
