Etymology

Description

It is a soft and ductile shiny white metal. It has good resistance to alkali, sulfuric and hydrochloric acid corrosion. It oxidizes immediately at a temperature of 933K. Vanadium has two naturally occurring isotopes and five radioisotopes. Among these, V-49 has the longest half-life at 337 days. Vanadium is widely used in the nuclear field. While the foil coats steel with titanium, vanadium-gallium tape is also used in the production of superconducting magnets. It was originally discovered by Mexican Andres Manuel del Rio in 1801. However, this discovery was not notable enough and in 1820, Swede Nils Gabriel Sefstron rediscovered vanadium. Metallic vanadium was isolated by Henry Enfield Roscoe in 1867. The name of the element comes from Vanadis, a Norse goddess. It is a silvery-white transition element. Vanadium is essential for ascidia. Rats and chickens are also known to need it. Metal dust poses a fire hazard. Additionally, it should not be forgotten that vanadium compounds are extremely toxic. The element can cause lung cancer if inhaled.

Etymological Description

It comes from Vanadis, one of the names of the Vanir goddess Freyja in Norse mythology. This name was given because its chemical compounds consisting of many colors look beautiful.

Production & Use

Sources

It is found in the minerals patronite (VS4), vanadinite [Pb5(VO4)3Cl] and carnotite [K2(UO2)2(VO4)2.3H2O]. The pure metal form is heated with carbon (C) and chlorine (Cl2) to obtain vanadium trichloride (VCl3). Afterwards, the resulting compound is heated with magnesium in an argon atmosphere to obtain its pure form.

Uses

It is used with other metals to make stronger and more durable alloys. Vanadium pentoxide (V2O5) is used as a catalyst, dye and color stabilizer.
