Vanadium(V) atomic and molecular weight, atomic number and elemental symbolVanadium is a Block D, Group 5, Period 4 element. Vanadium Bohr ModelThe number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electron configuration is [Ar] 3d3 4s2. The vanadium atom has a radius of and its Van der Waals radius is In its elemental form, CAS 7440-62-2, vanadium has a blue-silver-grey appearance. High Purity (99.999%) Vanadium (V) Metal Vanadium is found in fossil fuel deposits and 65 different minerals. Vanadium is not found free in nature; however, once isolated it forms an oxide layer that stabilizes the free metal against further oxidation. Although Vanadium was first discovered by Andres Manuel del Rio in 1801, metallic vanadium was not isolated until 1867 when Henry Enfield Roscoe extracted it from vanadium chloride (VCl3). Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology.

Vanadium is highly resistant to corrosion so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. High Purity (99.999%) Vanadium (V) Sputtering TargetVanadium's most important compound, vanadium pentoxide, is used as a catalyst for the production of sulfuric acid. Vanadium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). High Purity (99.999%) Vanadium Oxide (V2O3) PowderElemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Vanadium 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 powder and dense pellet form 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. Vanadium is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element. Safety data for Vanadium 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 Products tab below.
