American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. American Elements specializes in producing high purity Scandium Zirconium Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. 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 Inductively Coupled Plasma (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 such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Scandium as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.
Scandium is a Block D, Group 3, Period 4 element. The number of electrons in each of Scandium's shells is 2, 8, 9, 2 and its electronic configuration is [Ar] 3d1 4s2. In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is mildly toxic. Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum giving uses in aerospace and most recently, in racing bicycles and golf clubs. Doping zirconium oxide with scandium oxide produces a low temperature electrolyte in solid oxide fuel cells. Scandium information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Scandium was first discovered by Lars Nilson in 1879. The origin of the name, Scandium, comes from the Latin word 'Scandia' meaning Scandinavia. See Scandium research below.
Zirconium is a Block D, Group 4, Period 5 element. The number of electrons in each of Zirconium's shells is 2, 8, 18, 10, 2 and its electronic configuration is [Kr] 4d2 5s2. In its elemental form zirconium's CAS number is 7440-67-7. The zirconium atom has a radius of 159.pm and it's Van der Waals radius is 200.pm. Zirconium is non-toxic. Zirconium is primarily used in it's oxide or zirconia form. Zirconium dioxide has a high melting point (2,700° C) and a low thermal conductivity. Its polymorphism, however, restricts its widespread use in ceramic industry. During a heating process, zirconia will undergo a phase transformation process. The change in volume associated with this transformation makes the usage of pure zirconia in many applications impossible. Addition of some oxides, such as CaO, MgO, and Y2O3, into the zirconia structure in a certain degree results in a solid solution, which is a cubic form and has no phase transformation during heating and cooling. This solid solution material is termed as stabilized zirconia, a valuable refractory. Stabilized zirconia is used as a grinding media and engineering ceramics due to its increased hardness and high thermal shock resistivity. Stabilized zirconia is also used in applications such as oxygen sensors and solid oxide fuel cells due to its high oxygen ion conductivity.Zirconium was first discovered by William Gregor in 1791. The name Zirconium originated from the Persian word 'zargun' meaning gold color or gold-like. See Zirconium research below.
