Praseodymium is the third member of the lanthanide series, and a member of the rare-earth metals. In the periodic table, it appears between the lanthanides cerium to its left and neodymium to its right, and above the actinide protactinium. It is a ductile metal with a hardness comparable to that of silver. [ 10 ]
Praseodymium is a soft, silvery metal used in alloys for aircraft engines, flints, magnets and glass colouring. It is extracted from monazite and bastnaesite minerals and has no biological role.
21 cze 2013 · Praseodymium is a rare-earth metal that can be used as an alloying agent, a colorant and a doping agent. Learn about its discovery, word origin, electron configuration and more.
Praseodymium is used as a doping agent in fiber optics as signal amplifier. It is used to make 5% misch metal (mixed metal containing cerium, lanthanum and neodymium) to make flint for lighters. It is also used as an alloying additions to ferrous and non- ferrous alloys.
Praseodymium is a minor constituent of misch metal, which is used to make lighter flints and as alloying additions to ferrous and nonferrous alloys. The metal is also used as an addition to Nd 2 Fe 14 B permanent magnet alloys leading to a reduction of the amount of neodymium required.
