Vanadium

A white shiny metal, vanadium is also ductile and hard. It is not very susceptible to corrosion by alkali compounds, hydrochloric acid or sulfuric acid. It interacts less than other metals with neutrons from nuclear fission. It is both acidic and basic.

It is used for electricity storage in flux batteries. Some surgical steels contain vanadium. Vanadium blue contains this metal as a pigment. In compound form, it catalyzes the synthesis of sulfuric acid or maleic anhydride. Vanadium is also found in association with aluminum and Titanium in some jet engines.
