Oxide IonAmerican Elements specializes in producing Samaria doped Ceria (SDC), cerium oxide stabilized by various doping solid oxide fuel cell cathode and electrolyte cross section by SEM levels of yttrium oxide, a material that upon firing forms a highly ionically conductive thin film electrolyte layer for use in solid oxide fuel cell electrochemistry structures. Samarium Oxide 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. Samarium Oxide 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.

Cerium(Ce) atomic and molecular weight, atomic number and elemental symbolCerium is a Block F, Group 3, Period 6 element. The number of electrons in each of Cerium's shells is 2, 8, 18, 19, 9, 2 and its electronic configuration is [Xe]4f2 6s2. In its elemental form cerium's CAS number is 7440-45-1. The cerium atom has a radius of 182.5.pm and it's Van der Waals radius is 181.pm. Cerium is moderately toxic. Cerium is one of the products manufactured and distributed under the tradename AE Rare Earths. Cerium is the most abundant of the rare earths 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 aqueousCerium Bohr Model solutions.It is, therefore,Elemental Cerium strongly acidic and moderately toxic. It is also a strong oxidizer.The cerous state closely resembles the other trivalent rare earths. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, as the electrolyte for solid oxide fuel cells when doped with yttrium, gadolinium or samarium and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony. It is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolor glass by keeping iron in its ferrous state. The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass. Cerium was first discovered by W. von Hisinger in 1903. The element was named after the asteroid Ceres. See Cerium research below.

Samarium(Sm)atomic and molecular weight, atomic number and elemental symbol Samarium is a Block F, Group 3, Period 6 element. The number of electrons in each of Samarium's shells is 2, 8, 18, 24, 8, 2 and its electronic configuration is [Xe]4f6 6s2. In its elemental form samarium's CAS number is 7440-19-9. The samarium atom has a radius of 180.4.pm and it's Van der Waals radius is unknown. Samarium is somewhat toxic. Samarium is primarily utilized in the production of samarium-cobalt (Sm2Co17) permanent magnets. Samarium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compoundsElemental Samarium as Samarium Bohr Model submicron and nanopowder. It is also used in laser applications and for its dielectric properties. Samarium-cobalt magnets replaced the more expensive platinum-cobalt magnets in the early 1970s. While now overshadowed by the less expensive neodymium-iron-boron magnet, they are still valued for their ability to function at high temperatures. They are utilized in lightweight electronic equipment where size or space is a limiting factor and where functionality at high temperature is a concern. Applications include electronic watches, aeospace equipment, microwave technology and servomotors. Because of its weak spectral absorption band samarium is used in the filter glass on Nd:YAG solid state lasers to surround the laser rod to improve efficiency by absorbing stray emissions. Samarium was first discovered by Paul Emile Lecoq de Boisbaudran in 1879. Samarium is named after the mineral samarskite. See Samarium research below.
