Vanadium (V)

Definition - What does Vanadium (V) mean?

Vanadium (V) is a chemical element that is silvery-grey in color, ductile and malleable in nature. It is generally isolated artificially and passivates via the formation of an oxide layer, making it largely corrosion resistant.

Corrosionpedia explains Vanadium (V)

Vanadium has good corrosion resistance, particularly in the presence of alkalis, hydrochloric acid and brine. It has good structural strength and a low neutron cross section, making it ideal for use in nuclear applications. However, it is primarily used in the manufacturing of rust-resistant equipment and tools. Eighty percent of the vanadium produced today is used as a steel additive or in ceramics as a catalyst.

Some key properties of vanadium:

  • Atomic number: 23
