Rare-earth metals (REEs) are a group of 17 metallic elements including the 15 lanthanides,  yttrium (Y) and scandium (Sc), known for their unique magnetic, optical, and electronic properties. These materials are essential for advanced technologies, including electronics, optics, catalysts, clean energy, and materials research.

High-purity rare earth metals forms for alloying, magnetic materials, and thin-film deposition.
