    Applications 

    Praseodymium(III, IV) oxide, Pr6O11 is used in pigment in glass, optic and ceramic industries.It is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. 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. It has a number of potential applications in chemical catalysis, and is often used in conjunction with a promoter such as sodium or gold to improve its catalytic performance. It is widely used to convert CO to COin car exhaust.
