When was vanadium discovered and its uses

When was vanadium discovered is a question that some people might find interesting, especially those who are in the field of education. Vanadium was discovered in 1801 by a Swedish chemist called Nils Gabriel Sefstrôm. He discovered it while studying the mineral pyrolusite which is a type of ore. Nils Gabriel Sefstrôm, like many chemists before him, became interested in pyrolusite because it had been known to react with acids and give off a black coating of magnetite on its surface while doing so. Understanding Nils Gabriel Sefstrômn's work in more detail, it was noticed that the ore had a bright yellow color to it when inorganic compounds such as sulfur dioxide, sulfuric acid and potassium chloride were added.

This made him wonder if there was a new element present that was lighter than tin but heavier than iron. He tested this hypothesis by subjecting the ore to higher heat and pressure but he couldn't identify any other element that could have this particular property. He then tried deducing which elements should be present based on formulas of other known elements in the pyrolusite mineral. This resulted in his making a list of compounds with the element written as V (in German, Vanadium). This shows when was vanadium discovered.

Uses of Vanadium

1. Ingredients used to make stainless steel

This is the usual use of vanadium, as a means of manufacturing steel that is highly resistant to rust. When used in this way, the metal is usually alloyed with other elements such as chromium or nickel. The result is usually known as stainless steel.

2. Used to make very strong alloys in the aerospace industry

The metal has become a vital part of the aerospace industry and it especially useful when making spaceship parts that will be subjected to high temperatures and will need to be able to withstand ballistic impacts, because it absorbs energy during impact and expels it very quickly, releasing heat which greatly increases its resistance to stress.

3. Used in the making of magnets

Vanadium oxide is principally used for this purpose, although it is also used in smaller quantities for making batteries, making steel stronger and in the production of chemicals and fertilizers. Vanadium oxide is usually derived from the ore called vanadinite, which was originally named after vanadium.

4. A useful medicine in helping fight certain types of cancer

Vanadium disulfide is a compound that has been shown to improve the efficiency of chemotherapy treatment when fighting cancers such as osteosarcoma, pancreatic cancer and other cancers that are especially lethal if not dealt with quickly and effectively. It has also been shown to extend the life expectancy of mice with leukemia.

5. A useful medicine for diabetics

Vanadium-iron oxide has been seen to lower blood glucose levels in people with diabetes. It is normally used in the form of mineral mix to bind the element iron with the element vanadium, so that it can more easily absorb into a diabetic's circulatory system. This is made by putting it into a mixture that contains a type of clay known as montmorillonite and then watering it down with water. This can then be added to diabetic patients' drinking water to increase their intake of iron and vanadium, as well as keeping them from feeling hungry while they are undergoing treatment.

6. A useful component in solar cells

This is a more modern use of the element that has developed in recent years. There is a thin film of vanadium-gallium oxide that is used to make solar cells more efficient, since it has been observed that it can trap light at a level much higher than silicon, which is commonly used to make them. It also helps eliminate heat from the solar cell and this is important for reducing noise. This makes it more practical for the technology to be used by those who live in areas with a lot of direct sunlight. Vanadium-gallium oxide film has even been used to help improve photocopiers and barcode readers, as well as making computers run faster and phones work better in general.

7. Used as a catalyst to improve the performance of diesel engines

The element has been shown to be effective as a catalyst in improving the power and efficiency of diesel engines, and has been used this way in Mercedes Benzes, for example. It is normally mixed with iron oxide, which offsets its reactivity and makes it less reactive within a fuel system. It does this by reducing the amount of nitric oxide it produces when burning and avoiding particulate formation during combustion, hence reducing soot in exhaust gases and widespread destruction of the fuel system that can cause the engine to disintegrate completely after operating for long periods without being tuned or maintained.

In conclusions, when was vanadium discovered, can be used as a component in so many different kinds of products, that it is now hard to imagine life without it. All over the world, it seems, there are large numbers of people who use products that have vanadium in them on an almost daily basis, whether they realize it or not. This is what can be described as one of the most common elements in our planet and one of those that are most valuable to us even though we seldom realize its value.
