Praseodymium trifluoride Chemical Properties,Usage,Production

Uses

Praseodymium trifluoride, is the main raw materials for making Praseodymium Metal, and also applied in colour glasses and enamels. Praseodymium is present in the rare earth mixture whose Fluoride forms the core of carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Doping Praseodymium in Fluoride glass allows it to be used as a single mode fiber optical amplifier.

Chemical Properties

Praseodymium trifluoride is light green fine crystalline powder

Uses

Praseodymium(III) fluoride is used for vacuum deposition. It is used for making praseodymium metal, arc carbon additives. It is applied in color glasses and enamels. It is used in the motion picture industry for studio lighting and projector lights. Doping Praseodymium in Fluoride glass allows it to be used as a single mode fiber optical amplifier.
