Praseodymium metal is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native 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 easily burns at 150 °C to form praseodymium (III, IV) oxide.
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. Praseodymium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
