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.

Order Praseodymium (III, IV) oxide Pr6O11 / TREO: 99.5%.
