Iron 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.

Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Iron 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.

available for many specific states, forms and shapes on the product pages listed to the left. Elemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Nanoparticles and nanopowders provide ultra high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits.

Oxides are available in forms including powders and dense pellets for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Iron is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries.

Iron is a Block D, Group 8, Period 4 element. The electronic configuration is [Ar] 3d6 4s2. In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pm and it's Van der Waals radius is 200.pm.

All elemental metals, compounds and solutions may be synthesized in ultra high purity (e.g. 99.999%) for laboratory standards, advanced electronic, metallurgy and optical materials and other high technology advantages. Information is provided for stable (non-radioactive) isotopes. Organo-Metallic Iron compounds are soluble in organic or non-aqueous solvents. See Analytical Services for information on available certified chemical and physical analysis techniques including MS-ICP, X-Ray Diffraction, PSD and Surface Area (BET) analysis.

Iron was first discovered by Early Man.
