The following uses for praseodymium are gathered from a number of sources as well as from anecdotal comments. I'd be delighted to receive corrections as well as additional referenced uses (please use the feedback mechanism to add uses).
- used as a core material for carbon arc lights used by the motion picture industry
- salts 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
- Misch metal, used in making cigarette lighters, contains about 5% praseodymium metal
