I have compiled a list of sources for the elements that are available to the amateur chemist. Vanadium will be discussed here.
Vanadium is a bluish gray metal. It is rarely found as a pure metal but much more commonly found as an alloy with steel. Vanadium compounds are used as catalysts and vitamin supplements. Vanadium is a moderately toxic transition metal. Some sea creatures contain large amounts of vanadium.
In element form: Vanadium steel contains from 0.1 to 5% vanadium in it.
In compound form: Vanadyl sulfate is used in vitamin supplements. Bismuth yellow is made of bismuth vanadate.
Here is my sample of vanadium. It is a screwdriver blade composed of vanadium steel.
