neodymium

noun    (Concise Encyclopedia)

Metallic chemical element, chemical symbol Nd, atomic number 60. Silvery white in colour, it is a rare earth metal and one of the lanthanide series. It is a component of important alloys, among them misch metal (15% neodymium), used in lighter flints and various metallurgical processes. Alloyed with iron and boron, neodymium is the basis for powerful permanent magnets used in computer hard drives, lightweight earphones, and numerous other applications. Neodymium compounds are employed as ceramics glazes. The crude oxide counteracts the greenish cast imparted to glass by iron contaminants, and a very pure oxide is used to make a vivid purple glass. Neodymium is added to glass or other host materials to form the active elements for certain solid-state lasers. Glass containing a mixture of neodymium and praseodymium (another rare earth element) is used in glassblowers' goggles.
