Neodymium - Nd
Neodymium (Nd)
Neodymium is a silvery lanthanide metal that oxidises in air. It occurs in rare-earth minerals and is commonly recovered together with other lanthanides. Neodymium has a strong role in modern permanent-magnet technology.

Uses and applications
Neodymium–iron–boron magnets are among the strongest permanent magnets in common use. They are found in applications such as motors, generators, loudspeakers, and compact electronic equipment. Neodymium compounds are also used in some specialised glass and laser materials.
Neodymium and water treatment
Neodymium is not a routine water-treatment chemical. Water quality can be an important part of rare-earth extraction, refining, and magnet-recycling operations, where process solutions, wash waters, and residues require site-specific management.
Occurrence and environmental context
Neodymium occurs in minerals such as monazite and bastnäsite. Its release and mobility depend on the chemical form and conditions such as pH, dissolved ligands, and interactions with mineral surfaces.
Health and safety
Health effects depend on the specific neodymium compound and exposure route. Avoid inhaling dust and consult the relevant safety data sheet and occupational hygiene guidance when handling neodymium materials.
