Neodymium metal (Nd)-Rod

Characteristic

 

Neodymium is a chemical element with the symbol Nd and atomic number 60. Neodymium belongs to the lanthanide series and is a rare-earth element. It is a hard, slightly malleable silvery metal that quickly tarnishes in air and moisture.

Application

 

Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses. Another important use of neodymium is as a component in the alloys used to make high-strength neodymium magnets—powerful permanent magnets.
