American Elements specializes in producing high purity uniform shaped Nickel Chromium Pellets with the highest possible density and smallest possible average grain sizes for use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Pellet sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Pellets outside this range for ultra high puritythin film applications, such as fuel cells and solar energy layers. 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. See research below.
Nickel is a Block D, Group 4, Period 4 element. The number of electrons in each of Nickel's shells is 2, 8, 16, 2 and its electronic configuration is [Ar]3d8 4s2. In its elemental form nickel's CAS number is 7440-02-0. Nickel is sometimes found free in nature but is more commonly found in ores. The nickel atom has a radius of 149.pm and it's Van der Waals radius is 163.pm. Nickel and its compounds are considered to be carcinogenic. Nickel carbonyl is a very toxic gas. It is extensively alloyed with iron, chromium, molybdenum, tungsten and other metals produce stainless and other anti-corrosive steel and other corrosion-resistant alloys. It is highly electronically conductive and has many applications as a result. It is the basis of the nickel hydride battery. Most recently, its conductive properties have made it an ideal component for ceramic anode formulations used in oxygen generation and solid oxide fuel cell applications. Catalytic nickel is used to hydrogenate vegetable oils. Nickel additions to glass and ceramic glazes impart a bright green. It is also used in pigments for this purpose. Nickel information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Nickel was first discovered by Alex Constedt in 1751. The name originates from the German word 'kupfernickel' which means false copper from the illusory copper color of the ore. See Nickel research below.
Chromium is a Block D, Group 6, Period 4 element. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electronic configuration is [Ar] 3d5 4s1. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Hexavalent chromium is toxic. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green. Chromium 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. It is also used as a paint pigment for this purpose.Although chromium metal is an essential trace element, hexavalent chromium (Cr(VI)) is especially toxic and carcinogenic. Recently, chromites have formed the basis for cathode compositions for oxygen generation and fuel cell applications. Chromium information, including Technical Data, Safety Data and its High Purity properties, 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. Chromium was first discovered by Anders Ekeberg in 1802. Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color. See Chromium research below.
