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 Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. American Elements specializes in producing high purity Lead Phosphide 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. "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 nanoparticles. We also produce Lead as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.
Lead is a Block P, Group 14, Period 6 element. The number of electrons in each of Lead's shells is 2, 8, 18, 32, 18, 4 and its electronic configuration is [Xe] 4f14 5d10 6s2 6p2. In its elemental form lead's CAS number is 7439-92-1. The lead atom has a radius of 175.pm and it's Van der Waals radius is 202.pm. Lead and its compounds are poisonous. Lead is a bluish-white metal of bright luster, naturally occurring as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%). It is highly resistant to corrosion and can be used to contain corrosive liquids such as sulfuric acid. Great quantities of Lead, both as the dioxide and the metal, are used in batteries, cable covering, plumbing, and ammunition. Alloys include solder, type metal, and various antifriction metals and compounds. Lead is extremely effective at absorbing sound and vibration. It is also used as radiation shielding for X-ray equipment and nuclear reactors. Oxides of Lead are used in producing fine "crystal glass" and "flint glass" of a high index of refraction for achromatic lenses. Lead ceramics and crystalline material have a wide range of industrial and optical applications, including infrared detection and imaging. Lead-based semiconductors, such as lead telluride, lead selenide and lead antimonide are finding application in photovoltaic (solar energy) cells and infra red detectors. Lead was first discovered by Early Man. The origin of the name Lithium comes from the Greek word protos meaning "first". See Lead research below.
Phosphorus is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s2 3p3. In its elemental form Phosphorus's CAS number is 7723-14-0. The Phosphorus atom has a radius of 110.5.pm and it's Van der Waals radius is 180.pm. Although white phosphorus is very toxic, red phosphorus is not considered toxic. Phosphorus 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.
American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis.
