Neodymium is the fourth member of the lanthanide series. In the periodic table, it appears between the lanthanides praseodymium to its left and the radioactive element promethium to its right, and above the actinide uranium. Its 60 electrons are arranged in the configuration [Xe]4f 4 6s 2, of which the six 4f and 6s electrons are valence.
Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. 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) 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.
In the US, more than half of REEs are used for catalysts; ceramics, glass, and polishing are also main uses. [128] Other important uses of rare-earth elements are applicable to the production of high-performance magnets, alloys, glasses, and electronics. Ce and La are important as catalysts, and are used for petroleum refining and as diesel ...
Neodymium nickelate. [Nd+3]. [Ni+3]. [O-2]. [O-2]. [O-2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Neodymium nickelate is a nickelate of neodymium with a chemical formula NdNiO 3. In this compound, the neodymium atom is in the +3 oxidation state. [citation needed]
Applications of quantum mechanics include explaining phenomena found in nature as well as developing technologies that rely upon quantum effects, like integrated circuits and lasers. [note 1] Quantum mechanics is also critically important for understanding how individual atoms are joined by covalent bonds to form molecules.
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 [why?], 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 ...
