American Elements specializes in producing high purity Cadmium Circles with the highest possible densityHigh Purity (99.99%) Metallic Circleand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Circle sizes range from 1" to 8" in diameter and from 2mm to 1/2" thick. We can also provide Circles outside this range. 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. 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 Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. See safety data and research below and pricing/lead time above. We also produce Cadmium as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Cadmium(Cd) atomic and molecular weight, atomic number and elemental symbolCadmium is a Block D, Group 12, Period 5 element. The number of electrons in each of Cadmium's shells is 2, 8, 18, 18, 2 and its electronic configuration is [Kr] 4d10 5s2. In its elemental form cadmium's CAS number is 7440-43-9. The cadmium atom has a radius of 148.9.pm and its Van der Waals radius is 158.pm. Cadmium and its compounds are very toxic. Cadmium is a component of some of the lowest melting alloys; it is used in bearing alloys with low coefficients of friction and great resistance to fatigue. Cadmium is used extensively in electroplating, which accounts for about 60% of its use. It is also used in many types of solder,Elemental Cadmium for standard E.M.F. cells, for nickel-cadmium batteries, and as a barrier to control nuclear fission. Cadmium compounds are used in black and white television phosphors and in blue and green phosphors for color television tubes and CRT monitors.Cadmium Bohr Model Cadmium in glass and ceramic glazes creates a distinctive cadmium yellow. It forms a number of compounds, of which the sulfate is most common; the sulfide is used as a yellow pigment. Cadmium is similar to carbon in that it has a capacity to form stable covalently bonded molecular networks. Cadmium and its compounds are extremely toxic. Cadmium was first discovered by Fredrich Stromeyer in 1817. Cadmium, a common impurity in zinc ores, is isolated during the production of zinc. The name Cadmium originates from the Latin word 'cadmia' and the Greek word 'kadmeia'. See Cadmium research below.
