Applications
In glass and metallurgy industry, Praseodymium(III,IV) oxide use as additive of fluorescent powder, raw material for making praseodymium yellow and bright in color of ceramic glaze. It uses as colorant in glass industry that forms into green, which uses to imitate gem. It is raw material for praseodymium metal, Sm-Pr-Co permanent magnet material.
Praseodymium oxide uses as ceramic pigments, glass colorant, refractory ceramics. 96% Pr6O11 specially uses in producing yellow ceramic pigment (Zr-Pr). Adding 2~4% Pr6O11 in glass can show bright green. Due to electrical conductivity, it fits for preparing heat elements of oven. High pure Pr6O11 acts as luminescent materials, crystal material, fiber dopant, electronic ceramics and so on.
