• Sources of Vanadium:

  Found in the minerals patronite (VS4), vanadinite [Pb₅(VO₄)₃Cl], and carnotite [K₂(UO₂)₂(VO₄)₂.3H₂O]. Vanadium is usually produced as a by-product of refining other ores and from Venezuelan oils. Annual world wide production is around 7,000 tons.

• Uses of Vanadium:

  It is mixed with other metals to make very strong and durable alloys which are used in construction materials, tools, springs and jet engines. Vanadium pentoxide (V2O₅) is used as a catalyst, dye and color-fixer.

• Additional Notes:

  Many sources credit Nils Sefström with discovering vanadium in 1831, however, this is more of a rediscovery as it had already been discovered in A.M. del Rio in 1801.
