Praseodymium Oxide Nanoparticles (Pr6O11) – Properties, Applications

Nanoparticles research has gained momentum in the recent years mainly due to the unexpected behavior exhibited by the nanoparticles, with modified atomic and molecular properties.

Praseodymium oxide (Pr6O11) nanoparticles are available in the form of spray dried, non-spray and high purity powders. Some of the synonyms of these nanoparticles are hexapraseodymium undecaoxide and praseodymium (III, IV) oxide. These nanoparticles are eye irritants and affect the respiratory system when inhaled. Praseodymium belongs to Block F, Period 6 while oxygen belongs to Block P, Period 2 of the periodic table.
