For example, porous tantalum coatings are used in the construction of titanium implants due to tantalum's exceptional ability to form a direct bond to hard tissue. [74] Because tantalum is a non-ferrous, non-magnetic metal, tantalum implants are considered to be acceptable for patients undergoing MRI procedures.
Equipment such as medical electronics and space equipment that require high quality and reliability makes use of tantalum capacitors. An especially common application for low-voltage tantalum capacitors is power supply filtering on computer motherboards and in peripherals, due to their small size and long-term reliability.
Treatment of tantalum pentachloride with hexamethylbenzene (C 6 Me 6), aluminium, and aluminium trichloride gives [M(η 6-C 6 Me 6)AlCl 4] 2. [7] Tantalum-alkyne complexes [8] catalyze cyclotrimerizations. [9] [10] Some tantalum-alkyne complexes are precursors to allylic alcohols. [11] Tantalacyclopropenes are invoked as intermediates.
Lithium tantalate is used for nonlinear optics, passive infrared sensors such as motion detectors, terahertz generation and detection, surface acoustic wave applications, cell phones. Lithium tantalate is a standard detector element in infrared spectrophotometers .
Tantalum ores often contain significant amounts of niobium, which is itself a valuable metal.As such, both metals are extracted so that they may be sold. The overall process is one of hydrometallurgy and begins with a leaching step; in which the ore is treated with hydrofluoric acid and sulfuric acid to produce water-soluble hydrogen fluorides, such as the heptafluorotantalate.
The two cyclopentadienyl rings are in a bent conformation as confirmed by neutron diffraction studies where the ring-to-tantalum-to-ring bending angle is 139.9°. [4] The three hydrides lie in the same plane as the tantalum center with the three Ta-H bond distances being essentially equal (1.769(8) Å, 1.775(9) Å, and 1.777(9) Å).
Many oxides of tantalum are called tantalates. They are viewed as derivatives of "tantalic acid", hypothetic compounds with the formulas Ta 2 O 5 ·nH 2 O [ 1 ] or HTaO 3 [ 2 ] ). Examples of such tantalates are lithium tantalate (LiTaO 3 ), lutetium tantalate (LuTaO 4 ), neodymium tantalate (NdTaO 4 ) and lead scandium tantalate (PST or Pb ...
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.
