Vanadium: Element (V) of the periodic table

Vanadium: The versatile metal behind stronger steel and modern energy solutions

Transition metals like vanadium display multiple oxidation states, high melting points, and remarkable catalytic properties. These characteristics make vanadium crucial in steel production, energy storage, and industrial chemistry. In this article we explore vanadium’s properties, uses, and its importance in technology and industry.

Properties of vanadium

What does vanadium look like?

Vanadium is a hard, silvery-gray metal with a metallic sheen. Its lustrous surface reflects light and gives it a characteristic metallic appearance, similar to other transition metals used in alloys and industrial applications.

Will we ever run out of vanadium?

Vanadium is relatively abundant but not evenly distributed in the Earth's crust. Its availability is influenced by mining and extraction processes. While vanadium is not at immediate risk of depletion, demand in steel and battery industries can impact prices. Recycling and efficient extraction help maintain a steady supply.

Can vanadium be recycled?

Yes, vanadium is recyclable, especially from steel slag and used vanadium redox batteries. Recycling reduces environmental impact and ensures the metal remains available for industrial use.

Does vanadium have a biological role?

Vanadium is not essential for humans but can influence certain biological processes in trace amounts in some organisms. In humans, it has no recognized role and is primarily of industrial and scientific interest.

What is pure vanadium used for?

• Steel Alloys: Added to steel to increase strength, toughness, and resistance to wear and corrosion.
• Energy Storage: Vanadium redox flow batteries provide long-life, scalable energy storage solutions.
• Catalysis: Vanadium pentoxide is used as a catalyst in the production of sulfuric acid and other chemical processes.
• Superalloys: Vanadium is used in aerospace components and high-performance alloys.
• Research: Vanadium compounds are used in material science and chemical research.

What are the main compounds with vanadium?

• Vanadium(V) Oxide (V₂O₅) : Used as a catalyst in sulfuric acid production and other chemical reactions.
• Vanadium Chloride (VCl₃) : Used in research and as a precursor for other vanadium compounds.
• Vanadium Pentoxide (V₂O₅) : Employed in catalysis and chemical manufacturing.
• Vanadium Alloys : Alloys containing vanadium and other metals for high-strength steel and aerospace applications.

Where can vanadium be found?

Vanadium is primarily found in minerals like:

• Patrónite: A primary vanadium-bearing mineral.
• Vanadinite: Often mined as a source of vanadium.
• Magnetite deposits: Vanadium is extracted as a byproduct from vanadium-rich magnetite ores.
• Other minerals: Vanadium occurs in various titaniferous magnetite and phosphate minerals.

Main vanadium producers include China, Russia, South Africa, Brazil, and the United States, which have substantial vanadium mining and refining capabilities.

Is vanadium expensive?

Vanadium’s cost is moderate but fluctuates with steel demand, battery production, and global supply constraints. Its industrial importance often makes it a valuable commodity.

Who discovered vanadium?

Vanadium was discovered by Andrés Manuel del Río in 1801 in Mexico but was initially mistaken for chromium. It was correctly identified and named by Nils Gabriel Sefström in 1830 in Sweden, who named it "vanadium" after Vanadis, the Norse goddess of beauty, due to its colorful compounds.

Is vanadium dangerous?

Elemental vanadium is generally not highly toxic, but some vanadium compounds can be hazardous if inhaled, ingested, or in contact with skin. Appropriate safety measures should be observed in industrial and laboratory environments.
