Nd ( Neodymium )

Keterangan

      Neodymium reacts slowly with cold water and quickly with hot water. It quickly tarnishes in air and so is usually kept under paraffin or sealed in plastic.
      It exists in two allotropic forms, with a transformation from hexagonal to body-centred cubic taking place at 863K.

Nama lain (trademark, branding etc.)

Neodymium, Neodym, Neodimij, Néodyme, Neodym - r, Neodimio, Неодим

Aplikasi

       Neodymium is present in mischmetall up to 18%. This alloy is used in such products as cigarette lighters where a light flint operates. Neodymium is also a component, along with praseodymium, of didymia, a special glass used in goggles in glass blowing and welding. The element colours glass delicate shades of violet, wine-red and grey. It is used to make glass which transmits the tanning rays of the sun but not the harmful infrared rays.

Bahan Baku

Neodymium is a chemical element with the symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air.  It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is a fairly common element, no rarer than cobalt, nickel, and copper ore, and is widely distributed in the Earth's crust.
