Brief introduction
V: V element symbols, silver metal, VB clan in the periodic table, atomic number 23, atomic weight of 50.9414.Vanadium is a moderately reactive metal with valence +2, +3, +4 and +5.The compound with 5 valence state is the most stable, followed by 4 valence state. The compound with 5 valence state has the properties of oxygen Chemicalbook, while the compound with low price vanadium has the properties of reducing.The lower the valence state of vanadium, the more reductive it is.Ionization energy of 6.74 electron volts, with the ability to resist hydrochloric acid and sulfuric acid, and in the resistance to gas, salt, water corrosion performance is better than most stainless steel.Vanadium in the air is not oxidized, soluble in hydrofluoric acid,nitric acid and aqua regia.
Physicochemical property
Vanadium is a light gray or silvery white, malleable solid, glossy powder or molten lump.Insoluble in water;Corrosion resistant,
but soluble in nitric acid, hydrofluoric acid and concentrated sulfuric acid;It is eroded by alkali to form water-soluble vanadate.Acting as metal or nonmetal, Chemicalbook and form a variety of complex compounds.The properties of vanadium are similar to tantalum and niobium. The British chemist Roscoe studied its properties and determined that it is similar to tantalum and niobium, which laid the foundation for the three of them to build a subgroup in the periodic table of elements.

Agriculture application
Vanadium belongs to the class of elements that are not essential but beneficial to plant growth.It is a very useful nutrient for green algae, but the exact amount of vanadium required for higher plant growth has not been determined.Under the action of
nitrogen fixation, vanadium can be replaced by microorganisms such as nitrogen-fixing bacteria and rhizobium bacteria.In asparagus, rice, lettuce, barley, and corn Chemicalbook, vanadium induces increased growth.It has also been speculated that
vanadium may play a role in biological REDOX reactions.In the absence of molybdenum, vanadium stimulated the growth and nitrogenase activity of fishy algae.Low concentration of vanadium is conducive to the optimal growth of microorganisms and higher plants.Typically, the concentration of vanadium in plants is about 1ppm.

Medical application
Since phosphoric acid and Mg2+ ions are widely present in cells, the structure of VO-3 is similar to that of phosphoric acid, and the size of VO2+ and Mg2+ is similar (the ionic radius of the Chemicalbook is 160pm and 165pm), so they may interfere with the
biochemical reaction process of cells by competing binding ligands with phosphoric acid and Mg2+.It can inhibit ATP phosphohydrolase, ribozyme phosphofructokinase, phosphoglyceraldehyde kinase, 6-phosphogluconase, phosphotyrosine protein kinase.Therefore, vanadium into the cell Chemicalbook has a wide range of biological effects.Vanadium
compounds also have the advantages of relatively easy synthesis and low price, so the study of the hypotensive mechanism of vanadium compounds is conducive to the development and utilization of vanadium.

Industrial application
Vanadium has many excellent physical and chemical properties, so the use of vanadium is very wide, known as the metal "vitamin".The initial V is mostly used in steel. By refining the structure and grain of steel, the grain coarsening temperature is improved, thus increasing the strength, toughness and wear resistance of steel.V metal is widely used in special steel,superhard materials, hard alloy, can increase the strength of alloy, toughness, corrosion resistance, wear resistance and the ability to bear impact load;Used as additives for fast neutron reactor cladding materials, superconducting materials and special alloys.With the rapid development of science and technology, people's requirements for new materials are increasing day by day.Vanadium is widely used in non-steel fields, including aerospace, chemistry, battery, pigment, glass, optics, medicine and many other fields.
