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.
The following tables list the chemical properties of praseodymium oxide.
||Praseodymium [Xe]4f3 6s2
Oxygen [He] 2s2 2p4
Praseodymium oxide nanoparticles appear in the form of a brown powder. The table below provides the physical properties of these nanoparticles.
The thermal properties of praseodymium oxide nanoparticles are given in the table below:-
The following are the chief applications of praseodymium oxide:
- As a magnetic material
- As a catalyst
- Dried powder when mixed with the binder is useful in plasma spray guns and coating.
