- [Properties]
-
- Vanadium is described as a silvery-white or grayish-colored metal. It is
- fairly lightweight - somewhat heavier than aluminum, but lighter than iron.
- It is malleable and ductile, and resistant to corrosion by moisture, air,
- and even most acids and alkalis at room temperature. Its properties become
- less desirable at elevated temperatures, however, where vanadium readily
- combines with atmospheric oxygen and nitrogen.
- Vanadium has an unusually large number of different oxidation states and
- it combines with nearly all nonmetals. These facts account for the large
- number of compounds of vanadium.
- Iron and vanadium work well together and can be alloyed in any desired
- proportion. Ferrovanadium, for example, is an alloy of iron and a few other
- metals, plus 1% to 6% vanadium.
