Praseodymium

Description

Praseodymium resembles the typical trivalent rare earths; however, it will exhibit a +4 state when stabilised in a zirconia host. The element is found in most all light rare earth derivatives. It is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Much research is being done on its optical properties for use in amplification of telecommunication systems, including as a doping agent in fluoride fibers.

Praseodymium doped zirconia is a potential cathode for low temperature solid oxide fuel cell (SOFC) applications. It is also used in the scintillator for medical CAT scans. Praseodymium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder
