Metallic chemical element, one of the transition elements, chemical symbol Ta, atomic number
a hard gray lustrous metallic element that is highly corrosion-resistant; occurs in niobite and fergusonite and tantalite
Chemical symbol Ta 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-degree F
A rare nonmetallic element found in certain minerals, as tantalite, samarskite, and fergusonite, and isolated as a dark powder which becomes steel-gray by burnishing
A rare metal of silver white color having excellent corrosion resistance and a high melting point It is widely used for chemical process equipment and specialized aero-space and nuclear applications
It is a dense, hard, unreactive, silvery gray metal with an extremely high melting point (5,425 °F [2,996 °C]). Relatively rare, it occurs native in a few places. It is difficult to separate from niobium, the element above it in the periodic table, with which it shares many properties. The most important uses are in electrolytic capacitors, corrosion-resistant chemical equipment, dental and surgical instruments, tools, catalysts, components of electron tubes, rectifiers, and prostheses. Its compounds are relatively unimportant commercially; tantalum carbide is used in machine tools and dies
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
[ 'tan-t&l-&m ] (noun.) 1802. A New Latin word derived by Swedish chemist Anders Gustaf Ekeberg in 1802, from Latin tantalus,Chambers Dictionary of Etymology, Robert K. Barnhart (ed.), Chambers, 1988 named in honor of Tantalus.
