All element articles and their infoboxes use IUPAC spelling of elements and compounds. Notably, that is aluminium, sulfur, caesium, not aluminum, sulphur, cesium. For other English variant words (vapor vs. vapoUr) the infobox reads |engvar=. The parameter should be set in the article, and has options: enUS (or blank; default), enGB, enOED.

Niobium, is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the .
Tantal je kemijski element koji u periodnom sustavu elemenata nosi simbol Ta, atomski (redni) broj mu je 73, a atomska masa mu iznosi 180,94788(2).. To je vrlo tvrdi sivi sjajan metal. Čisti metal se može izvući u vrlo fine žice. Na izloženoj površini formira se oksidni film otporan na koroziju.
Tantalum was first used to create the first filaments for early light bulbs, but after time, tungsten replaced this. Tantalum was named after the Greek mythological figure, Tantalus. It was named after this because Tantalus was the father of Niobe, and they named Niobium after .
Oct 03, 2011· While tantalum and niobium are relatively depleted, compared to other incompatible elements, many primitive arc magmas have higher tantalum and niobium concentrations than MORB (Figure 14). This is particularly true of primitive continental arc lavas, both basalts and andesites.
The name comes from Niobe, a figure in Greek mythology, who was Tantalus' daughter. Tantalus, in turn, is the origin of the name for tantalum, a metal with similar physical and chemical properties as niobium, thus, adding to the difficulty of distinguishing between the two elements. Below is the historical Niobium price per metric ton.
Tantalum has the third highest melting point of any element. It is highly conductive of both heat and electricity. It is very strong and has the ability to resist corrosion even by very strong acids. Tantalum is sometimes found in niobium, and when it is it becomes chemically combined to find .

Areas covered include atomic structure, physical properties, atomic interaction, thermodynamics, identification, atomic size, crystal structure, history, abundances, and nomenclature.
Tantalum is a silvery white solid at normal pressure and temperature. We suggest this element at the purity of 99,95% in pellets or shots put inside a 7 mL glass vial with about 2 cm of diameter. High purity 99,99% Tantalum metal sheet 1,5cm long incredible shiny sample element 73 in .
Tantalum (Ta) has an atomic mass of 73. Find out about its chemical and physical properties, states, energy, electrons, oxidation and more.
Element category: transition metal. Tantalum is a lustrous, bluegray, ductile, hard metal which is highly resistant to corrosion. It is an excellent conductor of heat and electricity. The main use of tantalum is in the production of electronic components, mainly capacitors and some highpower resistors.
Applications for tantalum Tantalum consumption is dominated by capacitors for electronic equipment. Capacitors are electrical components that store energy electrostatically in an electric field, and are used in a wide variety of electric and electronic products.
Tantalum definition is a graywhite ductile acidresisting metallic element found combined in rare minerals (such as tantalite and columbite) and used especially in electronic components. a graywhite ductile acidresisting metallic element found combined in rare minerals (such as tantalite and columbite) and used especially in.
Tantalum is the rarest stable element in the universe, however, Earth has large deposits. Tantalum carbide (TaC) and tantalum hafnium carbide (Ta 4 HfC 5) are very hard and mechanically enduring. Large chunk of tantalum, 127 grams, 3 x 5 cm. Single pieces of tantalum, each about 1 cm in size.
tantalum generally accumulate in the later differentiates during crystallization of granites, and there is a tendency for tantalum to be concentrated relative to niobium in certain albitized or
Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, an antihero from Greek mythology. [4] Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant.
Tantalum has in recent years been turned to economic service, being employed, in the same manner as tungsten, for the production of the filaments employed in incandescent electric lighting. It is usually found associated with tantalum, the chief minerals containing these two elements being tantalite, columbite, fergusonite and yttrotantalite; it is also a constituent of pyrochlor, euxenite and samarskite.
Tantalum capacitors achieve high capacitance values through a combination of factors, including a tantalum pentoxide (Ta 2 O 5, εr = 27) dielectric, a large plate area (A), and a very thin dielectric thickness (d). The positively charged dielectric plate of a tantalum capacitor is formed from pure elemental grade tantalum powder that is pressed and sintered into a pellet.
Tantalum alloy (Ta) is ductile, easily fabricated, highly resistant to corrosion by acids, and a good conductor of heat and electricity and has a high melting point. The major use for tantalum is for the production of electronic components, mainly tantalum capacitors.
An alloying element in superalloys, of which it enhances the hightemperature strength. Being bioinert, it is used for implants, pins, etc. Yttrium tantalate YTaO4 is used in medical diagnosis. Recycling. Tantalum is recovered from slags resulting from the smelting of tin.
Tantalum is mined from various regions around the world, with most tantalum coming from either South America or Australia. It is often found together with nobium as well as the radioactive elements thorium and uranium, and has to be extracted from these other elements. Tantalum is naturally grayish in color with a hint of blue.
Tantalum Sheet / Tantalum Plate Introduction Tantalum (Ta) is a dark bluegray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid.
Tantalum is a very high melting point refractory metal of a slightly purplish hue. ACI Alloys stocks some pure tantalum sputtering targets and evaporation pieces for immediate delivery. We can also make many tantalum alloys. See tantalum in our "materials made" page for an idea of our capabilities–also try searching alphabetically on each...
