Praseodymium - Pr

Praseodymium is a soft malleable, silvery-yellow metal. it's a member of the lanthanide group of the table of elements. It reacts slowly with oxygen: when exposed to air it forms a green oxide that doesn't protect it from further oxidation. It's more immune to corrosion in the air than the opposite rare metals, but it still must be stored under oil or coated with plastic. It reacts rapidly with water.

Applications of Praseodymium

A major use of the metal is during an alloy utilized in cigarettes lighter flints. Praseodymium compounds have different uses: the oxide is employed in carbon electrodes for arc lighting, and it's known for its ability to offer glass a pleasant yellow color. This glass filters out the infrared, so it's utilized in the goggles which protect the eyes of welders. The salts are wont to color enamel and glass. Praseodymium is often used as an alloying agent with magnesium to make high-strength metals that are utilized in aircraft engines.

Praseodymium is one of the rare chemicals, which will be found in houses in equipment like color televisions, fluorescent lamps, energy-saving lamps, and glasses. All rare chemicals have comparable properties. the utilization of praseodymium remains growing, thanks to the very fact that it's suited to supply catalyzers and to shine glass.
