Tantalum is a chemical element; it has symbol Ta and atomic number 73. It is named after Tantalus, a figure in Greek mythology. [11] Tantalum is a very hard, ductile ...
Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta 2 O 5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings ...
Tantalum arsenide is a compound of tantalum and arsenic with the formula TaAs. It is notable as being the first topological Weyl semimetal that was identified and ...
The compound can also be prepared by direct reaction of tantalum metal with ethanol, in which case the overall equation is the same as that shown above for the electrochemical approach. [8] Since the 1970s, Bayer of Germany had been producing tantalum(V) ethoxide in Leverkusen, however following the break-up of Bayer, production moved to Heraeus.
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.
Tantalum-Carbon Bond Organotantalum chemistry is the chemistry of chemical compounds containing a carbon -to- tantalum chemical bond . A wide variety of compound have been reported, initially with cyclopentadienyl and CO ligands.
Tantalum boride films can be deposited from a gas mixture of TaCl 5-BCl 3-H 2-Ar in the temperature range 540–800 °C. TaB 2 (single-phase) is deposited at a source gas flow ratio (BCl 3 /TaCl 5 ) of six and a temperature above 600 °C.
Tantalum telluride (Ta Te 2) is a chemical compound of tantalum and tellurium.Tantalum also forms a tantalum rich telluride with the approximate formula Ta 1.6 Te that is unusual in that it forms dodecagonal chalcogenide quasicrystals, a formation that cannot occur in a normal crystal because it does not result in a periodic crystal lattice.
