American Elements specializes in producing high purity Platinum 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 Platinum as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Platinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f¹⁴ 5d⁹ 6s¹. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and its Van derWaals radius is 172.pm. Though it is one of the rarer and more expensive metals used in manufacturing, a highly efficient electrodeposition process unique to Platinum discovered by the National Institute of Standards and Technology (NIST) in December 2012 may lower the industrial costs of Platinum ultrathin films in the future. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does not oxidize in air at any temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Platinum is found in alluvial deposits and with iridium as platiniridium. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below.
