A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. They are the most widely used type of rare-earth magnet.
What is Neodymium? Neodymium is one of the more reactive lanthanides—a group of similar metallic elements numbered 57-71 on the periodic table. These 15 elements, plus scandium and yttrium, are termed “rare earth elements” (REEs).
Jun 21, 2013 · Neodymium is one of the more reactive lanthanide rare-earth metals and quickly oxidizes in air. The element should be kept under an oil or sealed tightly in a plastic material. The metal has a...
Neodymium is a chemical element; it has symbol Nd and atomic number 60. It is the fourth member of the lanthanide series and is considered to be one of the rare-earth metals. It is a hard, slightly malleable, silvery metal that quickly tarnishes in air and moisture.
May 11, 2018 · Overview. Neodymium was discovered in 1885 by Austrian chemist Carl Auer (Baron von Welsbach; 1858-1929). Auer found the new element in a mineral called didymia. Didymia, in turn, had been found in another complicated mineral known as ceria, originally found in Sweden in 1803. It took chemists nearly a century to completely analyze ceria.
Neodymium is a bright silver metal with a luster. It exists in two allotropic forms: α and β. Neodymium has chemical symbol is Nd with atomic number 60. Its atomic weight is 144.24. Its density at room temperature is about 7.01 g/cm 3. Its melting point is 1024 O C. Boiling point of neodymium is about 3074 O C. Chemical Characteristics.
Neodymium is a rare earth metal with the atomic number 60 and symbol Nd. A lustrous, silvery metal that tarnishes in air, neodymium is an essential component in various high-strength permanent magnets and optical devices. Classified as a metal, it is hard, somewhat malleable, and has a bright, silvery metallic luster. Historical Background.
