Praseodymium (Pr) Nanoparticles - Properties, Applications

Nanoparticles are microparticles that have narrow size distribution and atleast one dimension between 1 and 10 nm. Nanoparticles have wide range of potential applications in electronic, optical and biomedical fields.

Praseodymium is typical of the trivalent rare earth elements. It is highly used in ceramic and glass production because of its excellent optimum reflectance.

Praseodymium nanoparticles are available in high purity, ultra high purity, passivated, coated and dispersed forms.
