Praseodymium Metal Introduction

Praseodymium metal is a soft, silvery, malleable, and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to in natural form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air. To protect praseodymium for this reaction, praseodymium is usually stored in a sealed plastic container or covered with oil. Praseodymium also reacts quickly with hot water to form praseodymium hydroxide. Praseodymium metal tarnishes slowly in air and promptly burns at 150 °C to form praseodymium (III, IV) oxide.

Praseodymium metal is used as a high-strength alloying agent in the magnesium utilized parts for aircraft engines. It is an essential alloying agent in Neodymium-Iron-Boron magnets. Praseodymium is used to create high-power magnets notable for its strength and durability. It is also used in lighters, torch strikers, 'flint and steel' fire starters, etc. Praseodymium Metal can be further processed into various shapes of ingots, pieces, wires, foils, slabs, rods, discs, and powder.

Praseodymium Metal Applications

1. Praseodymium is used in goggles to protect the eyes of welders.
2. Praseodymium, combined with neodymium, is used to create high-power magnets due to its strength and durability.
3. When alloyed with magnesium, praseodymium creates a high strength metal used in aircraft engines.
4. Praseodymium is also used to color cubic zirconia yellow-green, to simulate the mineral peridot.
5. Praseodymium oxide can be used as oxidation catalysts.
