American Elements specializes in producing high purity uniform shaped Lead Chunk using crystallization, solid state and other ultra high purification processes such as sublimation. Standard Chunk pieces are amorphous uniform pieces ranging in size from 5-15 mm. 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 granules, 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 Lead as powder, ingot, pieces, pellets, disc, granules and in compound forms, such as oxide. Other shapes are available by request.

Lead(Pb) atomic and molecular weight, atomic number and elemental symbol 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 its 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. Elemental LeadIt is also used Lead Bohr Modelas 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 is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead minerals. 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.
