Tantalum History

Talk about Tantalum History,One of the denser natural elements,tantalum is related to niobium and vanadium, and share many of niobium's chemical and physical characteristics.

Discovered in Sweden over 200 years ago tantalum was not isolated until 182,and then only as an impure metal.

It was not until 1905 that a pure metal suitable for working was achieved.Its strengths are a high electrical capacitance per unit mass, a high melting point and excellent resistance to chemical attack.

More than 130 species of tantalum/niobium mineral exist, only some of which -tantalite, microlite, wodginite, euxenite, polycrase are so far being used by the tantalum industry as raw materilas. Tantalite,in the form of (Fe,Mn)(Ta,Nb)2O6 is the most important mineral tantalum extraction.
