tantalum's Usage Examples:

Antimony, bismuth, selenium, tellurium, chromic iron ore, tin, nickel, cobalt, vanadium, titanium, molybdenum, uranium and tantalum are produced in the United States in small amounts, but such production in several cases has amounted to only slight discoveries, and in general they are of little importance in the market.

The various improvements in electric illuminants, such as the Nernst oxide lamp, the tantalum and osmium incandescent lamps, and improved forms of arc lamp, enclosed, inverted and flame arcs, are described under Lighting: Electric.

Even so, the bulk of the tantalum market is, literally, in our hands in the form of the latest hi-tech gizmo.

Of minerals containing this element mention may be made of cassiterite or tinstone, Sn02, tin pyrites, Cu 4 SnS 4 + (Fe,Zn) 2 SnS 4; the metal also occurs in some epidotes, and in company with columbium, tantalum and other metals.

Ekeberg discovered an element, tantalum, in some Swedish yttrium minerals.

Blomstrand, and others, especially of Marignac, proved the identity of columbium, dianium and niobium, and that ilmenium was a mixture of columbium and tantalum.

The powder from which tantalum capacitors are made is of pure tantalum metal, with a typical particle size of 10µm.

It is then dissolved in hydrofluoric acid and heated in order to expel silicon fluoride; finally the columbium, tantalum and titanium fluorides are separated by the different solubilities of their double fluorides (C.

Columbium pentoxide (columbic acid), Cb205, is obtained from columbite, after the removal of tantalum (see above).

It is usually found associated with tantalum, the chief minerals containing these two elements being tantalite, columbite, fergusonite and yttrotantalite; it is also a constituent of pyrochlor, euxenite and samarskite.

Chemically related to vanadium are the two elements tantalum and columbium or niobium.

Wollaston unsuccessfully endeavoured to show that columbium and tantalum were identical.
