Tantalum | Ta Metal | Properties | Applications

Tantalum is an extremely rare transition metal that has a lustrous grey finish, similar in tone to platinum. Its discovery in 1802 was challenged by contemporary chemists who claimed it was not a new element but was an allotrope of niobium. The two are almost chemically-identical and are still difficult to distinguish from one another today.
