Zinc RockSimilar to naturally occurring rocks, American Element's Zinc Rocks are imperfect in shape in size, yet absolutely pure in quality. This shape is achieved through a process called casting. American Elements specializes in producing high purity uniform shaped Zinc Rocks 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). Zinc rocks are chunks of zinc, lumpy and uneven in appearance. Rocks are available in custom sizes including dimensions suitable for ultra high purity thin 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 such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. See research below. We also produce Zinc as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request. Zinc rocks appear unprocessed. Chemically, zinc rocks are the same as other zinc products.

Zinc(Zn) atomic and molecular weight, atomic number and elemental symbolZinc (atomic symbol: Zn, atomic number: 30) is a Block D, Group 12, Period 4 element with an atomic weight of 65.38. The number of electrons in each of zinc's shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d10 4s2. Zinc Bohr ModelThe zinc atom has a radius of 134 pm and a Van der Waals radius of 210 pm. Zinc was discovered by Indian metallurgists prior to 1000 BC and first recognized as a unique element by Rasaratna Samuccaya in 800. Zinc was first isolated by Andreas Marggraf in 1746.Elemental Zinc In its elemental form, zinc has a silver-gray appearance. It is brittle at ordinary temperatures but malleable at 100 °C to 150 °C. It is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore deposits. It is the 24th most abundant element in the earth's crust and the fourth most common metal in use (after iron, aluminum, and copper). The name zinc originates from the German word "zin," meaning tin.

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Shipping documentation includes a Certificate of Analysis and Material Safety Data Sheet (MSDS). Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes.
