Oct 20, 2021· Tantalum as an investment can be a rather contentious topic among finance experts. Others call it a conflict resource and have linked the use of the metal to the war in the African country once known as Zaire. This war is sometimes called the African World War, and it involved 9 countries and about 20 separate armed groups.

Mar 20, 2015· Niobium and tantalum are considered chemically similar as they fall within the same vertical group as vanadium in the periodic table. Similar to tantalum, niobium alloys have found wide use in joint arthroplasty, especially for high stress applications as composites of niobium and tantalum are both highly biocompatible.
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.
Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates. Three types of niobium and tantalum deposits are: carbonatite‐hosted deposits ...
Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties.
