American Elements specializes in producing high purity uniform shaped Calcium Oxide Pellets with the highest possible density and smallest possible average grain sizes for use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Pellet sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Pellets outside this range for ultra high puritythin film applications, such as fuel cells and solar energy layers. 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 Calcium Oxide as pieces, tablets, powder, and sputtering target. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems.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. Other shapes are available by request.
Calcium is a Block S, Group 2, Period 4 element. The number of electrons in each of Calcium's shells is 2, 8, 8, 2 and its electronic configuration is [Ar] 4s2. In its elemental form calcium's CAS number is 7440-70-2. The calcium atom has a radius of 197.4.pm and it's Van der Waals radius is 200.pm. Calcium is a member of the alkaline earth elements. Calcium is an essential metal for living organisms and is non-toxic. Its primary commercial application is in its metallic form as a reducing agent in the production of other metals. In iron and steel production it is added to the melt to remove oxygen, sulfur and carbon. The various calcium compounds have wide application in food, pharmaceutical and cosmetics. It is used in small doses in alloys of copper and beryllium. It is used in dietary supplements and food production because it has been shown to improve bone and dental health. Calcium information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Calcium was first discovered by Sir Humphrey Davy in 1808. The name calcium originates from the Latin word 'calics' meaning lime. See Calcium research below.
