NEODYMIUM Usage And Synthesis
General DescriptionNeodymium is the most abundant of the rare earths after Cerium and Lanthanum. It shows similar characteristics to the other trivalent Lanthanides.
Primary applications include lasers, glass coloring and tinting, dielectrics and, most importantly, as the fundamental basis for Neodymium-Iron-Boron (Nd2Fe14B) permanent magnets.
Neodymium has a strong absorption band centered at 580 nm, which is very close to the human eye's maximum level of sensitivity making it useful in protective lenses for welding goggles. It is also used in CRT displays to enhance contrast between reds and greens. It is highly valued in glass manufacturing for its attractive purple coloring to glass.
Neodymium is included in many formulations of barium titanate, used as dielectric coatings and in multi-layer capacitors essential to electronic equipment.
Yttrium-Aluminum-Garnet (YAG) solid state lasers utilize neodymium because it has optimal absorption and emitting wavelengths. Nd-based YAG lasers are used in various medical applications, drilling, welding and material processing.
Neodymium has an unusually large specific heat capacity at liquid-helium temperatures, so is useful in cryocoolers.
Probably because of similarities to Ca2+, Nd3+ has been reported to promote plant growth. Rare earth element compounds are frequently used in China as fertilizer.
It is still a popular additive in glasses. Neodymium is also used to make some of the strongest permanent magnets. These magnets are widely used in electrical motors, generators and some other electronics such as microphones, loudspeakers and computer hard disks. Neodymium is also used with other substrate crystals to make high-powered infrared lasers.
Neodymium Metal is mainly used in manufacturing very powerful permanent magnets-Neodymium-Iron-Boron magnets, and also are applied in making specialty superalloy and sputtering targets. Neodymium is also used in the electric motors of hybrid and electric automobiles, and in the electricity generators of some designs of commercial wind turbines.
Chemical Propertiesgrey metal ingot
HistoryIn 1841 Mosander extracted from cerite a new rose-colored oxide, which he believed contained a new element. He named the element didymium, as it was an inseparable twin brother of lanthanum. In 1885 von Welsbach separated didymium into two new elemental components, neodymia and praseodymia, by repeated fractionation of ammonium didymium nitrate. While the free metal is in misch metal, long known and used as a pyrophoric alloy for light flints, the element was not isolated in relatively pure form until 1925. Neodymium is present in misch metal to the extent of about 18%. It is present in the minerals monazite and bastnasite, which are principal sources of rare-earth metals. The element may be obtained by separating neodymium salts from other rare earths by ion-exchange or solvent extraction techniques, and by reducing anhydrous halides such as NdF3 with calcium metal. Other separation techniques are possible. The metal has a bright silvery metallic luster. Neodymium is one of the more reactive rare-earth metals and quickly tarnishes in air, forming an oxide that splits off and exposes metal to oxidation. The metal, therefore, should be kept under light mineral oil or sealed in a plastic material. Neodymium exists in two allotropic forms, with a transformation from a double hexagonal to a body-centered cubic structure taking place at 863°C. Natural neodymium is a mixture of seven isotopes, one of which has a very long half-life. Twenty-seven other radioactive isotopes and isomers are recognized. Didymium, of which neodymium is a component, is used for coloring glass to make welder’s goggles. By itself, neodymium colors glass delicate shades ranging from pure violet through wine-red and warm gray. Light transmitted through such glass shows unusually sharp absorption bands. The glass has been used in astronomical work to produce sharp bands by which spectral lines may be calibrated. Glass containing neodymium can be used as a laser material to produce coherent light. Neodymium salts are also used as a colorant for enamels. The element is also being used with iron and boron to produce extremely strong magnets. These are the most compact magnets commercially available. The price of the metal is about $4/g. Neodymium has a low-to-moderate acute toxic rating. As with other rare earths, neodymium should be handled with care.
UsesNeodymium salts, electronics, alloys, colored glass, (especially in astronomical lenses and lasers), to increase heat resistance of magnesium, metallurgical research, yttrium-garnet laser dope, gas scavenger in iron and steel manufacture
DefinitionMetallic element having atomic number 60, group IIIB of the periodic table, aw 144.24, valence of 3. A rare-earth element of the lanthanide (cerium) group. There are seven isotopes
Hazard(Salts) Irritant to eyes and abraded skin
Safety ProfileHuman systemic effects by intracerebral route: blood changes. It may be an anticoagulant lanthanoid. Care in handling is advised. Flammable in the form of dust when exposed to heat or flame. Slight explosion hazard in the form of dust when exposed to flame. Can react violently with air, halogens, N2.Violent reaction with phosphorus above 4OOOC. Many of its compounds are poisons.
