American Elements: Gadolinia doped Ceria Sputtering Target (GDC) Supplier & Tech Info

American Elements specializes in producing Gadolinia doped Ceria Sputtering Target (GDC), cerium oxide stabilized by various doping levels of gadolinium oxide, solid oxide fuel cell cathode and electrolyte cross section by SEM

solid oxide fuel cell cathode and electrolyte cross section by SEM

a material that upon firing forms a highly ionically conductive thin film electrolyte layer for use in solid oxide fuel cell electrochemistry structures. Gadolinium 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 Yttria doped Ceria (YDC). Even higher conductivity can be achieved with American Elements Scandia doped Zirconia (SCZ) and Yttria doped Bismuth Oxide. Gadolinium Oxide doped Cerium Oxide is also available in a powder for tape casting, air spray, extrusion and sputtering fuel cell applications and as an ink for screen printing. Gadolinia 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.

Our standard Sputtering Targets for thin film are available monoblock or bonded with dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devises as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications. Research sized targets are also produced as well as custom sizes and alloys. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Induction Plasma Spectrometry (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. We can also provide targets outside this range in addition to just about any size rectangular, annular, or oval target. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes nanoparticles.

Gadolinium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f⁷5d¹6s². In its elemental form gadolinium's CAS number is 7440-54-2. The gadolinium atom has a radius of 178.7.pm and it's Van der Waals radius is unknown. Gadolinium is utilized for both its high magnetic moment (7.94µB) and in phosphors and scintillator material. When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. Gadolinium 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.

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.
