About Praseodymium(III) Oxide

Oxide IonPraseodymium(III) Oxide is a highly insoluble thermally stable Praseodymium source suitable for glass, optic and ceramic applications. Praseodymium(III) Oxide is generally immediHigh Purity (99.999%) Praseodymium Oxide (Pr2O3) Powderately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Praseodymium is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems.

Synonyms

Dipraseodymium trioxide; praseodymium(3+) oxide

Related Elements

See more Praseodymium products. Praseodymium (atomic symbol: Pr, atomic number: 59) is a Block F, Group 3, Period 6 element with an atomic weight of 140.90765. Praseodymium Bohr Model The number of electrons in each of praseodymium's shells is 2, 8, 18, 21, 8, 2 and its electron configuration is [Xe]4f3 6s2. The praseodymium atom has a radius of 182 pm and a Van der Waals radius of 239 pm. Praseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. Elemental PraseodymiumUnlike other rare-earth metals, which show antiferromagnetic and / or ferromagnetic ordering at low temperatures, praseodymium is paramagnetic at any temperature above 1 K. Praseodymium is found in the minerals monazite and bastnasite. Praseodymium was discovered by Carl Auer von Welsbach in 1885. The origin of the element name comes from the Greek words prasios didymos, meaning green twin.
