Application
Praseodymium fluoride is the main raw materials for making Praseodymium Metal and also applied in color glasses and enamels; when mixed with certain other materials, Praseodymium produces an intense clean yellow colour in glass.
Praseodymium fluoride is mainly used in laboratory reagents, fiber doping, laser materials, fluorescent materials, optical fiber, optical coating materials, electronic materials and so on.
