PRASEODYMIUM Usage And Synthesis
UsesPraseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. The element is found in most all light rare earth derivatives.
It is highly valued for ceramics as a bright yellow pigment in praseodymium doped zirconia because of its optimum reflectance at 560 nm.
Much research is being done on its optical properties for use in amplification of telecommunication systems, including as a doping agent in Fluoride fibers.
Praseodymium is present in the rare earth mixture whose Fluoride forms the core of carbon arc lights which are used in the motion picture industry for studio lighting and projector lights.
Doping Praseodymium in Fluoride glass allows it to be used as a single mode fiber optical amplifier.
It is also used in the scintillator for medical CAT scans.
As an alloying agent with Magnesium to create high-strength metals that are used in aircraft engines.
Praseodymium compounds give glasses and enamels a yellow color.
Praseodymium Metal, is used as high-strength alloying agent in the Magnesium used in parts of aircraft engines. It is an important alloying agent in Neodymium-Iron-Boron magnets. Praseodymium is used to create high-power magnets notable for their strength and durability. It also used in lighters, torch strikers, 'flint and steel' fire starters, etc.
Chemical Propertiesgrey powder
HistoryIn 1879, Lecoq de Boisbaudran isolated a new earth, samaria, from didymia obtained from the mineral samarskite. Six years later, in 1885, von Welsbach separated didymia into two others, praseodymia and neodymia, which gave salts of different colors. As with other rare earths, compounds of these elements in solution have distinctive sharp spectral absorption bands or lines, some of which are only a few Angstroms wide. Praseodymium occurs along with other rare-earth elements in a variety of minerals. Monazite and bastnasite are the two principal commercial sources of the rare-earth metals. Ion-exchange and solvent extraction techniques have led to much easier isolation of the rare earths and the cost has dropped greatly. Thirty-seven isotopes and isomers are now recognized. Praseodymium can be prepared by several methods, such as by calcium reduction of the anhydrous chloride or fluoride. Misch metal, used in making cigarette lighters, contains about 5% praseodymium metal. Praseodymium is soft, silvery, malleable, and ductile. It was prepared in relatively pure form in 1931. It is somewhat more resistant to corrosion in air than europium, lanthanum, cerium, or neodymium, but it does develop a green oxide coating that splits off when exposed to air. As with other rare-earth metals it should be kept under a light mineral oil or sealed in plastic. The rare-earth oxides, including Pr2O3, are among the most refractory substances known. Along with other rare earths, it is widely used as a core material for carbon arcs used by the motion picture industry for studio lighting and projection. Salts of praseodymium are used to color glasses and enamels; when mixed with certain other materials, praseodymium produces an intense and unusually clean yellow color in glass. Didymium glass, of which praseodymium is a component, is a colorant for welder’s goggles. The metal (99.9% pure) is priced at about $4/g.
UsesPraseodymium salts, ingredient of mischmetal, core material for carbon arcs, colorant in glazes and glasses, catalyst, phosphors, lasers.
DefinitionPr. Metallic element of atomic number 59, group IIIB of the periodic table, one of the rare earth elements of the lanthanide group, aw 140.9077, valences = 3, 4. No stable isotopes.
