Vanadium is a soft and ductile, gray-white metal. It has good resistance to corrosion by alkalis, sulfuric and hydrochloric acid. It oxidizes readily at about 933 K. Vanadium has good structural strength and a low fission neutron cross section, making it useful in nuclear applications. Although a metal, it shares with chromium and manganese the property of having valency oxides with acid properties.
Common oxidation states of vanadium include +2, +3, +4 and +5. A popular experiment with ammonium vanadate (NH4VO3), reducing the compound with zinc metal, can demonstrate colorimetrically all four of these vanadium oxidation states. A +1 oxidation state is rarely seen.

Applications
Approximately 80% of vanadium produced is used as ferrovanadium or as a steel additive. Other uses;
In such alloys as:
specialty stainless steel, e.g. for use in surgical instruments and tools.
rust resistant and high speed tool steels.
mixed with aluminium in titanium alloys used in jet engines and high-speed airframes
Vanadium steel alloys are used in axles, crankshafts, gears, and other critical components.
It is an important carbide stabilizer in making steels.
Because of its low fission neutron cross section, vanadium has nuclear applications.
Vanadium foil is used in cladding titanium to steel.
Vanadium-gallium tape is used in superconducting magnets (175,000 gauss).
Vanadium(V) oxide (vanadium pentoxide, V2O5) is used as a catalyst in manufacturing sulfuric acid (via the Contact process) and maleic anhydride. It is also used in making ceramics.
Glass coated with vanadium dioxide (VO2) can block infrared radiation (and not visible light) at some specific temperature.
Electrical fuel cells and storage batteries such as Vanadium redox batteries.
Added to corundum to make simulated Alexandrite jewelry.
Vanadate electrochemical conversion coatings for protecting steel against rust and corrosion

Vanadium is a soft silvery white toxic metallic element used in steel alloys; it occurs in several complex minerals including carnotite and vanadinite. Vanadium is a chemical element in the periodic table that has the symbol V and atomic number 23. A rare, soft and ductile element, vanadium is found combined in certain minerals and is used mainly to produce certain alloys.
Vanadium(V) oxide (V2O5), commonly known as vanadium pentoxide, is the most important compound of vanadium. Upon heating it can reversibly lose oxygen to the air. Related to this is its the ability to catalyse the delivery of oxygen from the air to compounds such as sulfur dioxide, benzene and naphthalene, which is the basis for its industrial use as a catalyst in the manufacture of sulfuric acid, maleic anhydride and phthalic anhydride, respectively. It is believed that Vanadium is probably essential to growth and involved in fat metabolism. A Vanadium deficiency can increase blood cholesterol and triglyceride levels
Vanadium, when present in small amounts in certain ferrous alloys, can significantly improve their properties. Manufacturers of automobiles and machinery recognized the toughness and fatigue resistance of vanadium alloys as far back as the early 1900's, incorporating the alloys in axles, crankshafts, gears, and other critical components. Vanadium has been used together with aluminum to give the required strength in titanium alloys used in jet engines and high-speed airframes.
