Praseodymium is a soft, silvery, lustrous element, which may be cut with a knife. It is reactive and develops a green oxide coating, which spalls off in air. It is somewhat more resistant to corrosion in air than europium, lanthanum, cerium, or neodymium. Dilute acids also attack it, and as such the metal is generally stored in an inert atmosphere or in mineral oil.

Materials: Praseodymium’s primary use is as an alloying agent with magnesium to create high-strength metals used in aircraft engines. Praseodymium is among the most refractory substances known and is also used in automotive exhaust catalytic converters. Magnets:  Praseodymium can be used as a substitute for neodymium in super magnets. Electronics: Praseodymium forms the core of carbon arc lights, which are used in the film industry for studio lighting and projector lights.

التطبيق والاستخدام

Praseodymium can be found in the Earth’s crust with a typical concentration of 8 ppm (parts per million). Pr is not rare, as it is found in a variety of minerals, although the minerals belonging to the monazite and bastnäsite groups are considered the most significant sources in commercial applications.

Praseodymium is used to • Aircraft engines • Electronics • Permanent Magnet • Super magnets • Battery Alloys • Automotive catalytic converters • Studio lighting • Projector lights.
