Neodymium content in the crust of 0.00239%, mainly in monazite and bastnaesite. 7 kinds of naturally occurring isotopes of neodymium: Neodymium 142,143,144,145,146,148,150, 142 Nd highest levels. 　　Neodymium is a silvery white metal, melting point 1024 ° C, density of 7.004 g / cm ³. Neodymium is one of the most active of the rare earth metals, darkens rapidly in air to form oxides; react slowly in cold water, hot water in rapid response. Neodymium-doped yttrium aluminum garnet can replace ruby ​​and neodymium glass laser materials do, neodymium and praseodymium glass do goggles. 　　-------------------------------------------------- ------------------------------ 　　● Neodymium 　　(Nd) 　　nǚ ㄋ ㄩ 　　◎ a metallic element, the color yellow, rare earth metals. 1885 by the von 韦尔塞巴赫 discovery. With the birth of the elements praseodymium, neodymium element also came into being, the arrival of neodymium rare earth elements active in the field, play an important role in the field of rare earth, and about the rare earth market. 　　Source: element present in monazite from the water after dehydration neodymium chloride reduction with calcium metal, or by melting of anhydrous neodymium chloride electrolysis system. 　　Elements Uses: used in the manufacture of special alloys, electronic instruments and optical glass. In terms of manufacturing laser equipment, has important applications. 　　Element symbols: Nd 　　Relative atomic mass: 144.2 　　Common valence; +3 　　Electronegativity; 1.14 　　External electronic arrangement: 4f4 6s2 　　Extranuclear arrangement; 2,8,18,22,8,2 　　Isotopes and Radiation: * Nd-142 Nd-143 Nd144 (put α [2.1E15y]) Nd-145 Nd-146 Nd-147 [10.98d] Nd-148 Nd-149 [1.72h] Nd-150 　　The content of elements in the sun: 0.003 (ppm) 　　Content elements in seawater: Pacific surface 0.0000018 (ppm) 　　Content of the crust: 38 (ppm) 　　Crystal structure: hexagonal lattice cell. 　　Cell parameters: a = 365.8 pm, b = 365.8 pm, c = 1179.9 pm, α = 90 °, β = 90 °, γ = 120 ° 　　Oxidation states: Main Nd +3, Other Nd +2, Nd +4 　　Vickers Hardness: 343MPa 　　Sound propagation speed in which: 2330 (m / S) 　　Ionization energy (kJ / mol) 　　M - M + 529.6 　　M + - M2 + 1035 　　M2 + - M3 + 2130 　　M3 + - M4 + 3899 　　Bulk modulus: 31.8GPa 　　Atomization enthalpy: 322kJ / mol @ 25 ℃ 　　Heat capacity: 27.45J / (mol · K) 　　Conductivity: 0.0157 10 ^ 6 / (cm · Ω) 　　Thermal conductivity: 16.5W / (m · K) 　　Heat of fusion: 7.140 (kJ / mol) 　　Heat of vaporization: 273.0 (kJ / mol) 　　Atomic volume: 20.6 (cc / mol) 　　Content element in the universe: 0.01 (ppm) 　　Since Mosangdeer have discovered lanthanum, erbium and terbium later, chemist special attention from various countries have been found in the separation of rare earth elements to new elements. Separating elements of the oxide in the discovery of two new samarium and gadolinium same time, the 1885 from the Austrian chemist 韦尔塞巴赫 didymium (then considered a rare earth element) in the oxide, one is named To neodidymium, was later simplified to neodymium, the element symbol Nd. 　　Neodymium, praseodymium, gadolinium, samarium, are to be considered from a rare earth Yan idymium was separated out. Since their discovery, didymium is no longer reserved. And it is their discovery opens the door to the third discovery of rare earth elements, rare earth elements are found in the third stage. But this is only half finished third stage of the work. The exact cerium should open the door or complete separation of cerium, yttrium and the other half of the door will open or complete separation of yttrium. 　　Neodymium rare earth with its unique position in the field, over the years become a market attention. Is the largest user of the metal neodymium NdFeB permanent magnet materials. The advent of NdFeB permanent magnets, rare earth high-tech field has injected new vigor and vitality. High energy product NdFeB magnets, known as contemporary "King of the permanent magnet," with its excellent performance is widely used in electronics, machinery and other industries. The successful development of the Alpha Magnetic Spectrometer, marking the magnetic energy of NdFeB magnets has entered the world-class level. Neodymium is also used in non-ferrous materials. Add 1.5-2.5% of magnesium or an alloy of neodymium, can improve the high temperature properties of the alloy, gas tightness and corrosion resistance, is widely used as aerospace materials. Further, neodymium-doped yttrium aluminum garnet laser beam generating a short, widely used in industry thin material thickness of 10mm or less welding and cutting. In health care, the neodymium-doped yttrium aluminum garnet laser instead of a scalpel is used to disinfect a wound or surgical removal. Neodymium is also used in glass and ceramic materials, rubber additives and colorants. With the development of science and technology, expand and extend, the rare earth element neodymium technology sector will have a broader use of space.
