Praseodymium oxide | Pr6O11 | Praseodymium (III, IV) oxide
Praseodymium (III, IV) oxide is a chemical compound of the elements praseodymium
[Pr] and oxygen [O] and belongs to the group of metal oxides.
Praseodymium (III, IV) oxide is a black, odorless solid that is practically
insoluble in water. The trivalent praseodymium is represented twice, the
tetravalent praseodymium is represented four times. Formally it can be
understood as Pr2O3 ? 4 PrO2. It crystallizes in the cubic crystal system in the
fluorite structure, with 1/12 of the oxygen sites remaining unoccupied. It
decomposes on contact with water vapor to praseodymium (IV) oxide and
praseodymium (III) hydroxite. Praseodymium (III, IV) oxide is used for coloring
glass and ceramics.
