The Vanadium is a metal which exhibits the hardness average , almost blue steel. Although it is a little known metal, it is quite valuable in the manufacturing industry due to its malleable and ductile qualities and because it is highly resistant to corrosion. It is a trace mineral that is also found in many foods . Very small amounts are considered necessary for normal bone growth. Most of the studies on vanadium have been done in animals . Because few human clinical trials have been completed, it is not recommended for any diseaseor condition. However, it can have an effect on blood sugar in people with diabetes.
- Symbol : V
- Atomic number : 23
- Group: 5

- It has four different states of oxidation .
- It is a soft, ductile, silver- colored metal.
- Vanadium and its compounds are toxic and must therefore be handled with great care.
History and discovery
The etymological origin of the word vanadium comes from the name given to the Scandinavian deity Vanadis , a name that means goddess of beauty , love and fertility . This goddess was one of the most important and also most curious figures in Norse and Scandinavian mythological accounts . It was discovered by the Spanish scientist and naturalist Andrés Manuel del Río, who in 1801 came across this element while analyzing vanadinite minerals.
Who discovered vanadium
In 1801, Andrés Manuel del Río found this element that he named Erythronium . Later, in 1805, a group of scientists of French origin said that the discovery was simply an impure form of chromium and although del Río knew they were wrong, he accepted it. In the year 1830, vanadium was ” rediscovered ” by the Swedish chemist Nils Gabriel Sefström , who gave the element its name due to its beautiful multi-colored compounds . Finally, in 1867, the English chemist Sir Henry Enfield Roscoe was able to isolate the element in a pure form.
One of its main properties is that it has good resistance to corrosion by alkali, sulfuric acid, hydrochloric acid and seawater, this because it can quickly form an oxide layer that protects it. In a powdery state it is capable of burning in air. It is easily oxidized above 660 ° C and can dissolve in oxidizing acids or hot in sulfuric.
Where is it located
It occupies the 22nd position of the elements most abundantly found in the earth’s crust , although it is rarely found naturally in its metallic form . It is very rare to find it as a free element within nature, but it can be found in around 65 different minerals , including magnetite, vanadinite, carnotite, and patronite. It can also be found in phosphate rock and some crude oils . It is generally obtained by heating crushed mineral in the presence of carbon and chlorine to produce vanadium trichloride, which is then heated with magnesium in an atmosphereargon. About 98 percent of the mined vanadium ore comes from South Africa , Russia and China .
What is it for
Vanadium can commonly be used in new batteries that can store large amounts of energy almost indefinitely, which are essential for the proper operation of remote wind or solar farms . You can add small percentages to create alloys of steel exceptionally light, resistant and more elastic. Henry Ford was the first person to use it on an industrial scale , on the 1908 Model T automobile chassis , and today the vast majority of it is used on structural steel , primarily to construct bridges and buildings.
According to scientists, it has not yet been confirmed that the human body needs vanadium to survive. However, it has been shown that it can be useful in secreting some hormones , managing cholesterol and blood sugar levels. Among the foods that contain vanadium we can mention the following:
- The shellfish are a good source of vanadium.
- Some herbs and spices such as black pepper, parsley, and dill.
- The wheat .
- Sunflower seeds, peanuts and olive oil .
