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 ...
The phenomenon of pyroelectric fusion has been demonstrated using a lithium tantalate crystal producing a large enough charge to generate and accelerate a beam of deuterium nuclei into a deuterated target resulting in the production of a small flux of helium-3 and neutrons through nuclear fusion without extreme heat or pressure.
There are 2 parts per million of tantalum in the Earth's crust, making it the 51st most abundant element there. Soil contains on average 1 to 2 parts per billion of tantalum, and seawater contains 2 parts per trillion of tantalum. A typical human contains 2.9 parts per billion of tantalum. Tantalum is found in the minerals tantalite and ...
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 ...

With the addition of squarate or perchlorate, the tantalum complex dimerises in acetonitrile, with their respective chelating ligands bridging the Ta centres. These seven-coordinate complexes of the form TaMe 3 L 2 , where L is a bidentate monoanion, are markedly more thermally stable than their precursor, decomposing in the range 80 - 120°C.
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.
