Praseodymium(III, IV) oxide, REacton®, 99.99% (REO)


Chemical Properties

Formula Weight
Melting point
Insoluble in water. Moderately soluble in strong mineral acids.


Praseodymium(III, IV) oxide is used in pigment in glass, optic and ceramic industries. Praseodymium-doped glass, called didymium glass is used in welding, blacksmithing, and glass-blowing goggles due to its blocking property of infrared radiation. It is employed in the solid state synthesis of praseodymium molybdenum oxide, which is used as a semiconductor.


Hygroscopic and air sensitive. Incompatible with strong oxidizing agents.
