American Elements specializes in producing yttria doped ceria (YDC), 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. Yttrium Oxide doped Ceria belongs to a class of doped Ceria compounds with ionic conductivity exceeding Yttria stabilized Zirconia (YSZ) electrolytes. These include Samarium doped Ceria (SDC) and Gadolinium doped Ceria (GDC). Even higher conductivity can be achieved with American Elements Scandia doped Zirconia (SCZ) and Yttria doped Bismuth Oxide. Yttrium 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. Yttria 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 is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f26s2. 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 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 aqueous solutions. It is, therefore, strongly acidic. 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.

Yttrium is a Block D, Group 3, Period 5 element. The electronic configuration is [Kr] 4d1 5s2. In its elemental form yttrium's CAS number is 7440-65-5. The yttrium atom has a radius of 177.6.pm and it's Van der Waals radius is 200.pm. Yttrium has the highest thermo-dynamic affinity for oxygen of any element. This characteristic is the basis for many of its applications. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the “yttrics” for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. Yttrium 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 compounds as submicron and nanopowder. Some of the many applications of yttrium include in ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors.Yttria stabilized zirconium oxide are used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces and as an electrolyte in solid oxide fuel cells.
