Neodymium is present in significant quantities in the 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. Neodymium is fairly common—about as common as cobalt, nickel, or copper—and is widely distributed in the Earth's crust. [10]
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. [1] They are the most widely used type of rare-earth magnet .
Neodymium(III) carbonate is the carbonate of neodymium where neodymium exhibits the +3 oxidation state. It can be obtained by reacting neodymium(III) chloride with ammonium bicarbonate in water or from the hydrolysis of neodymium(III) chloroacetate: [14] 2Nd(C 2 Cl 3 O 2) 3 + 3H 2 O → Nd 2 (CO 3) 3 + 6CHCl 3 + 3CO 2 Neodymium acetate powder
Masato Sagawa (佐川眞人; born August 3, 1943, in Tokushima, Japan) is a Japanese scientist and entrepreneur, and the inventor of the sintered permanent neodymium magnet (NdFeB). Sagawa was awarded the Japan Prize and IEEE Medal for Environmental and Safety Technologies for his efforts.
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

Didymium glasses. Didymium (Greek: δίδυμο, twin) is a mixture of the elements praseodymium and neodymium.It is used in safety glasses for glassblowing and blacksmithing and filter lenses for flame testing, especially with a gas ()-powered forge, where it provides a filter that selectively blocks the yellowish light at 589 nm emitted by the hot sodium in the glass without having a ...
Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd 2 O 3. It forms very light grayish-blue hexagonal crystals. [ 1 ] The rare-earth mixture didymium , previously believed to be an element , partially consists of neodymium(III) oxide.
