A hard grey lustrous metallic element that is highly resistant to corrosion; occurs in niobite and fergusonite and tantalite
Tantalum (previously known as tantalium) is a chemical element with the symbol Ta and atomic number 73. A rare, hard, blue-gray, lustrous transition metal, tantalum is highly corrosion resistant and occurs naturally in the mineral tantalite, always together with the chemically similar niobium. ...
A metallic chemical element (symbol Ta) with an atomic number of 73
A metal with a texture similar to titanium, but a color similar to gold. Used by Omega for the gold-like trim on certain titanium watches. Many of these watches are also available in titanium with real gold trim.
A hard blue grey metal that has the symbol Ta.
A grey, heavy, and very hard metal. Tantalum is used to make avariety of alloys at high melting point and high strength. Tantalum is completely immune to body liquids and is a non-irrititating material.
A by-product of tin processing, this refractory metal is used as a barrier to corrosion of chemical processing and carbide cutting tools, and still-growing use as electronic capacitors and filaments. Melts at 2415 degrees Fahrenheit.
Ordinary aluminium electrolytic capacitors are rather large for many uses. In applications where size is of importance tantalum capacitors may be used. These are much smaller than the aluminium electrolytics and instead of using a film of oxide on aluminium they us a film of oxide on tantalum. ...
