American Elements: Zinc Oxide Powder Supplier & Tech Info

American Elements specializes in producing spray dry and non-spray dry high purity Zinc 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 (See also Nanotechnology Information and Quantum Dots) also produce very high surface areas. Our standard Powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns 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 (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Zinc 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. See research below. Other shapes are available by request.

Zinc is a Block D, Group 12, Period 4 element. The electronic configuration is [Ar] 3d¹⁰ 4s². In its elemental form zinc's CAS number is 7440-66-6. The zinc atom has a radius of 133.5.pm and it's Van der Waals radius is 139.pm. Zinc is a bluish-white, lustrous metal. It is brittle at ordinary temperatures but malleable at 100 to 150 o C. It is a fair conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. It has unusual electrical, thermal, optical, and solid-state properties that have not been fully investigated. The metal is employed to form numerous alloys with other metals. Brass, nickel, silver, commercial bronze, soft solder, and aluminum solder are some of the more important alloys. Large quantities of zinc are used to produce die castings, which are used extensively by the automotive, electrical, and hardware industries. Zinc is also used extensively to galvanize other metals such as iron to prevent corrosion. Zinc oxide is widely used in the manufacture of paints, rubber products, cosmetics, pharmaceuticals, floor coverings, plastics, printing inks, soap, storage batteries, textiles, electrical equipment, and other products. Zinc sulfide is used in making luminous dials, X-ray and TV screens, and fluorescent lights The chloride and chromate are also important compounds. Zinc is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.
