Description

Terbium (Tb): Magnetic Refrigeration Technology, Magneto-Optic Storage Material, High-Performance NdFeB Additive

Terbium is a silvery-white malleable metal with melting point 1356°C, boiling point 3230°C, density 8.22 g/cm³. Magnetic at room temperature. Naturally occurs with one stable isotope and 20 radioactive isotopes. Hexagonal crystal lattice. Soluble in dilute acids, reacts slowly with water. Highly reactive. Must be stored in inert gas or vacuum containers.

Applications

  1. Industrial magnetic refrigeration technology
  2. Magneto-optical storage materials
  3. High-performance NdFeB additives

Production Method
After separating terbium from other rare earths via ion exchange/solvent extraction, metallothermic reduction prepares metallic terbium. Unlike calcium reduction, lithium reduction occurs in gas phase. The lithium reduction reactor has two heating zones, combining reduction and distillation. Anhydrous TbCl₃ 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, TbCl₃ vapor reacts with lithium vapor, depositing terbium 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 TbCl₃.
