See research below. American Elements specializes in producing high purity Potassium 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 Potassium as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.
Potassium is a Block S, Group 1, Period 4 element. The number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is not toxic. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium research below.
PACKAGING SPECIFICATIONS FOR BULK & RESEARCH QUANTITIES
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). Bullion and bar forms are best if purchasing solely for physical possession and risk exposure.
