About Cerium Oxide, Praseodymium-doped

Oxide IonAmerican Elements specializes in producing Cerium Oxide, Praseodymium-doped, cerium oxide stabilized by various doping solid oxide fuel cell cathode and electrolyte cross section by SEM levels of Praseodymium, a material that upon firing forms a highly ionically conductive thin film electrolyte layer for use in solid oxide fuel cell electrochemistry structures. Praseodymium doped Ceria belongs to a class of doped Ceria compounds with ionic conductivity exceeding yttria stabilized zirconia (YSZ) electrolytes. These include yttria doped ceria (YDC) and gadolinium doped ceria (GDC). Even higher conductivity can be achieved with American Elements Scandia doped Zirconia (SCZ) and Yttria doped Bismuth Oxide. Praseodymium-doped Cerium Oxide is available in a powder for tape casting, air spray, extrusion and sputtering fuel cell applications and as an ink for screen printing. Samaria doping levels are available at 10% and 20% and as specified by customer. American Elements provides guidance on firing parameters, doping levels, and thermal expansion matching with American Elements' cathode and anode cell layers.

See more Cerium products. Cerium (atomic symbol: Ce, atomic number: 58) is a Block F, Group 3, Period 6 element with an atomic weight of 140.116. The number of electrons in each of cerium's shells is 2, 8, 18, 19, 9, 2 and its electron configuration is [Xe]4f2 6s2. Cerium Bohr ModelThe cerium atom has a radius of 182.5 pm and a Van der Waals radius of 235 pm. In its elemental form, cerium has a silvery white appearance. Cerium is the most abundant of the rare earth metals. It is characterized chemically by having two valence states, the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueous solutions. Elemental CeriumIt is, therefore, strongly acidic and moderately toxic. It is also a strong oxidizer. The cerous state closely resembles the other trivalent rare earths. Cerium is found in the minerals allanite, bastnasite, hydroxylbastnasite, monazite, rhabdophane, synchysite and zircon. Cerium was discovered by Martin Heinrich Klaproth, Jöns Jakob Berzelius, and Wilh elm Hisinger in 1803 and first isolated by Carl Gustaf Mosander in 1839. The element was named after the asteroid Ceres.

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.
