Vanadium 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.

Vanadium Bohr ModelVanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium 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. In honor of its beautiful multi-colored compounds, Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology.

Vanadium facts, including appearance, CAS #, and molecular formula and safety data, research and properties are 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 High Purity (99.999%) Vanadium Oxide (V2O3) Powderas 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. Vanadium is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries.

Vanadium is a Block D, Group 5, Period 4 element. The number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electronic configuration is [Ar] 3d3 4s2. In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element.

High Purity (99.999%) Vanadium (V) Sputtering TargetAll elemental metals, compounds and solutions may be synthesized in ultra high purity (e.g. 99.999%) for laboratory standards, advanced electronic, thin fillm deposition using sputtering targets and evaporation materials, metallurgy and optical materials and other high technology applications. Information is provided for stable (non-radioactive) isotopes. Organo-Metallic Vanadium 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.

Vanadium was first discovered in Mexico City by Andres Manuel del Rio, a Spanish born and European educated Mexican mineralogist, in 1801.

Safety Data and Biological Role. The safety data for vanadium metal, nanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the left margin. Vanadium compounds, in small quanties, are necessary in the diet of rats and chicks. Deficiencies of Vanadium cause reduced growth and impaired reproduction. Vanadium is also essential to sea squirts.
