Praseodymium Oxide, also called Praseodymia, used to colour glasses and enamels; when mixed with certain other materials, Praseodymium produces an intense clean yellow colour in glass. Component of didymium glass which is a colourant for welder's goggles, also as important additive of Praseodymium yellow pigments. Praseodymium Oxide in solid solution with ceria, or with ceria-zirconia, have been used as oxidation catalysts. It can be used to create high-power magnets notable for their strength and durability.
