About Chromium Oxide Powder

Oxide IonHigh Purity (99.999%) Chromium Oxide (Cr2O3) PowderAmerican Elements specializes in producing spray dry and non-spray dry high purity Chromium Oxide Powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in 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). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard powder particle sizes average in the range of- 325 mesh,- 100 mesh, < 10 micron and submicron (< 1 micron) and our spray dried powder with binder provides an extremely narrow particle size distribution (PSD) for use in thermal and plasma spray guns and other coating applications. We can also provide many materials in the nanoscale range. 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 and in the form of solutions and organometallics. We also produce Chromium Oxide as pellets, pieces, tablets, and sputtering target. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. 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 Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Other shapes are available by request.

See more Chromium products. Chromium (atomic symbol: Cr, atomic number: 24) is a Block D, Group 6, Period 4 element with an atomic weight of 51.9961. Chromium Bohr ModelThe number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Chromium was first discovered by Louis Nicolas Vauquelin in 1797. It was first isolated in 1798, also by Louis Nicolas Vauquelin. The chromium atom has a radius of 128 pm and a Van der Waals radius of 189 pm. In its elemental form, chromium has a lustrous steel-gray appearance. Elemental ChromiumChromium is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it tranforms into a paramagnetic solid. The most common source of chromium is chromite ore (FeCr2O4). Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color.
