[31], As in the cases of other refractory metals, the hardest known compounds of tantalum are nitrides and carbides. We use cookies on this site to enhance your user experience. [24] The ground state of 180Ta has a half-life of only 8 hours. He was born in Sweden and graduated from the University of Uppsala in 1788. It is also the rarest primordial isotope in the Universe, taking into account the elemental abundance of tantalum and isotopic abundance of 180mTa in the natural mixture of isotopes (and again excluding radiogenic and cosmogenic short-lived nuclides). Discovery: Tantalum was discovered by Anders Ekeberg in 1802. It is a rare, grey, heavy, hard but ductile, metal with a high melting point that reacts with HF and fused alkalis. The element name comes from the Greek mythological character Tantalos, father of Niobe. Tantalum is capable of capturing oxygen and nitrogen by forming nitrides and oxides and therefore helped to sustain the high vacuum needed for the tubes when used for internal parts such as grids and plates. Tantalum was discovered in Sweden in 1802 by Anders Ekeberg, in two mineral samples – one from Sweden and the other from Finland. Tantalum was discovered by Anders G. Ekeberg in 1802, in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. The minerals of Ytterby, Sweden were a particular interest. Discovered by: Anders Gustaf Ekenberg: Common Compounds: Tantalum carbide (TaC) Tantalum chloride (TaCl 5) Tantalum nitride (TaN) Tantalum pentoxide (Ta 2 O 5) Tantalum telluride (TaTe 2) Interesting facts: It is highly corrosion-resistant. Values in freshwaters fare little better, but, in all cases, they are probably below 1 ng L−1, since ‘dissolved’ concentrations in natural waters are well below most current analytical capabilities. He embarked on a teaching career at Uppsala where he presented chemical expositions and analysed minerals. The primary mining of tantalum is in Australia, where the largest producer, Global Advanced Metals, formerly known as Talison Minerals, operates two mines in Western Australia, Greenbushes in the Southwest and Wodgina in the Pilbara region. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment, and as a substitute for platinum. [17] Early investigators had only been able to produce impure tantalum, and the first relatively pure ductile metal was produced by Werner von Bolton in Charlottenburg in 1903. The team discovered that tantalum-187's gamma-ray 'fingerprint' was characteristic of a prolate (American football) shape but simultaneously with a hint of an oblate (pancake) shape. Tantalum was discovered by the Swedish chemist Anders Ekeberg, who extracted the metal from mineral samples. Physical Properties of Tantalum. During gravitational separation of the ores from placer deposits, not only is cassiterite (SnO2) found, but a small percentage of tantalite also included. [39] Whereas the large-scale producers of niobium are in Brazil and Canada, the ore there also yields a small percentage of tantalum. [27], Tantalum forms compounds in oxidation states −III to +V. This would transmute the tantalum into the radioactive isotope 182Ta, which has a half-life of 114.4 days and produces gamma rays with approximately 1.12 million electron-volts (MeV) of energy apiece, which would significantly increase the radioactivity of the nuclear fallout from the explosion for several months. The names columbium and niobium were both used to identify this element for almost another century, with columbium being preferred in the Americas. Because of the size and weight advantages, tantalum capacitors are attractive for portable telephones, personal computers, automotive electronics and cameras. [42][43], It is estimated that there are less than 50 years left of tantalum resources, based on extraction at current rates, demonstrating the need for increased recycling. It was discovered by Anders Gustaf Ekenberg in 1802. Marignac developed a procedure in 1866 to achieve their separation via the use of potassium double fluoride salts of tantalum and niobium. In modern times, the separation is achieved by hydrometallurgy. Niobium is not a very rare element. [73] Values in soils are close to 1 ppm and thus to UCC values. Discovered by: Anders Gustaf Ekenberg: Common Compounds: Tantalum carbide (TaC) Tantalum chloride (TaCl 5) Tantalum nitride (TaN) Tantalum pentoxide (Ta 2 O 5) Tantalum telluride (TaTe 2) Interesting facts: It is highly corrosion-resistant. )[19] Anders Ekeberg wrote "This metal I call tantalum ... partly in allusion to its incapacity, when immersed in acid, to absorb any and be saturated. [31], Tantalum halides span the oxidation states of +5, +4, and +3. [59], Tantalum is also used to produce a variety of alloys that have high melting points, strength, and ductility. In the story, he had been punished after death by being condemned to stand knee-deep in water with perfect fruit growing above his head, both of which eternally tantalized him. Closely associated with niobium in ores and in properties, tantalum was discovered (1802) by the Swedish chemist Anders Gustaf Ekeberg and named after the mythological character Tantalus because of the tantalizing problem of dissolving the oxide in acids. The two names are related. ), Swedish chemist who in 1802 discovered the element tantalum. The minerals of Ytterby, Sweden were a particular interest. [5] Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It was thought tantalum … Tantalum has a shaky history and origin since it was discovered by multiple people who taught that it was just a plain old mineral. Coltan, the industrial name for a columbite–tantalite mineral from which niobium and tantalum are extracted,[45] can also be found in Central Africa, which is why tantalum is being linked to warfare in the Democratic Republic of the Congo (formerly Zaire). The Wodgina mine was reopened in January 2011 after mining at the site was suspended in late-2008 due to the global financial crisis. [29], Tantalum pentoxide (Ta2O5) is the most important compound from the perspective of applications. [14][40], World tantalum mine production has undergone an important geographic shift since the start of the 21st century when production was predominantly from Australia and Brazil. Niobium can be found in nature only in compound state. Tantalum is a chemical element with the symbol Ta and atomic number 73. Several steps are involved in the extraction of tantalum from tantalite. It hydrolyzes readily to an oxychloride. All rights reserved. Tantalum is estimated to make up about 1 ppm[36] or 2 ppm[28] of the Earth's crust by weight. The first refinery has enough capacity to supply 3–4% of annual global demand. He was born in Sweden and graduated from the University of Uppsala in 1788. Ekeberg was born in Sweden and graduated from the University of Uppsala in 1788. Wires made with metallic tantalum were used for light bulb filaments until tungsten replaced it in widespread use. [58], The major use for tantalum, as the metal powder, is in the production of electronic components, mainly capacitors and some high-power resistors. Hard but malleable, tantalum is used as a wire and in electrical components, mobile phone capacitors, chemical equipment and medical instruments. Tantalum was discovered by the Swedish chemist Anders Ekeberg, who extracted the metal from mineral samples. There was no dispute concerning his conclusion until Heinrich Rose, in 1844, was able to distinguish these two elements by their differences in valence state, with columbium exhibiting +3 and +5 states and tantalum only +5 as stable entities. Disclaimer, TANTALUM-NIOBIUM INTERNATIONAL STUDY CENTER, © 2020 T.I.C. Tantalum is extremely inert and is therefore formed into a variety of corrosion resistant parts, such as thermowells, valve bodies, and tantalum fasteners. Website Delivered as a Service by. Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Alloyed with other metals, it is also used in making carbide tools for metalworking equipment and in the production of superalloys for jet engine components, chemical process equipment, nuclear reactors, missile parts, heat exchangers, tanks, and vessels. In nature, tantalum is mostly present in form of minerals. A year later, Ekeberg discovered a new element that he named tantalum. [10] After Friedrich Wöhler confirmed these results, it was thought that columbium and tantalum were the same element. The first person to discover tantalum was a man named Anders G. Ekeberg. Beginning in 2007 and through 2014, the major sources of tantalum production from mines dramatically shifted to the DRC, Rwanda, and some other African countries. The United States Geological Survey reports in its yearbook that this region produced a little less than 1% of the world's tantalum output in 2002–2006, peaking at 10% in 2000 and 2008. Tantalus was a son of Zeus, the major Greek god. In 1801, English chemist Charles Hatchett (1765-1847) discovered a new element that he named niobium. The beta phase is hard and brittle; its crystal symmetry is tetragonal (space group P42/mnm, a = 1.0194 nm, c = 0.5313 nm), Knoop hardness is 1000–1300 HN and electrical resistivity is relatively high at 170–210 µΩ⋅cm. What is Tantalum? Most commonly encountered are oxides of Ta(V), which includes all minerals. Anders Gustaf Ekeberg (1767-1813) discovered and named tantalum in 1802. Discovery: Tantalum was discovered by Anders Ekeberg in 1802. [26], Tantalum can be used as a target material for accelerated proton beams for the production of various short-lived isotopes including 8Li, 80Rb, and 160Yb. Oxides of tantalum in lower oxidation states are numerous, including many defect structures, and are lightly studied or poorly characterized. Word origin: Tantalum is named after a Greek mythological character, Tantalos. Tantalite (Fe, Mn) mineral is commonly used for the extraction of tantalum. Tantalum is not solderable. Origin of name : from the Greek word " Tantalos " meaning " father of Niobe " (Greek mythology, (tantalum is closely related to niobium in the periodic table). However, this discovery was the subject of much debate because a year earlier Charles Hatchett had discovered … The minerals of Ytterby, Sweden were a particular interest. Pollution linked to human use of the element has not been detected. Anders Gustav Ekeberg, Swedish chemist who in 1802 discovered the element tantalum. At levels of 2500 mg/m3, tantalum is immediately dangerous to life and health. Tantalum (Ta) is an unsung hero in modern metallurgy. Tantalum was discovered by a man named Anders Gustaf Ekenberg, who was a Swedish chemist. Instead of requiring the input oxide and output metal to be in liquid form, tantalum electrolysis operates on non-liquid powdered oxides. Tantalum was discovered by Anders G. Ekeberg in 1802, in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. Anders Ekeberg in 1802. Lanthanum tantalate (LaTaO4) contains isolated TaO3−4 tetrahedra. VAT number: BE0414.408.447 RPM Nivelles Ekeberg discovered tantalum in 1802, while he … [68] Because tantalum is a non-ferrous, non-magnetic metal, these implants are considered to be acceptable for patients undergoing MRI procedures. The anion [TaF7]2- is used for its separation from niobium. [71] The latest value for upper crust concentration is 0.92 ppm, and the Nb/Ta(w/w) ratio stands at 12.7. The lower halides TaX4 and TaX3, feature Ta-Ta bonds.[31][28]. This method has been supplanted by solvent extraction from fluoride-containing solutions of tantalum.[14]. [64] Tantalum greatly increases the armor penetration capabilities of a shaped charge due to its high density and high melting point. [70], Tantalum receives far less attention in the environmental field than it does in other geosciences. Tantalum was discovered by Anders Ekeberg in 1802 [1]. [33][63], The high melting point and oxidation resistance lead to the use of the metal in the production of vacuum furnace parts. [34][35] Diverse salts and substituted derivatives are known for the hexacarbonyl [Ta(CO)6]− and related isocyanides. [67] The high stiffness of tantalum makes it necessary to use it as highly porous foam or scaffold with lower stiffness for hip replacement implants to avoid stress shielding. Although Ta occurs as various minerals, it is conveniently represented as the pentoxide, since most oxides of tantalum(V) behave similarly under these conditions. The scientific community ca… The Occupational Safety and Health Administration (OSHA) has set the legal limit (permissible exposure limit) for tantalum exposure in the workplace as 5 mg/m3 over an 8-hour workday. Tantalum is also produced in Thailand and Malaysia as a by-product of the tin mining there. One such extraneous element was pelopium, proposed by Heinrich Rose in the 1840s. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. He concluded that the two oxides, despite their difference in measured density, were identical and kept the name tantalum. sputtering, chemical vapor deposition or electrochemical deposition from an eutectic molten salt solution. Tantalum was discovered in Sweden in 1802 by Anders Ekeberg, in two mineral samples – one from Sweden and the other from Finland. Discovered by. (If he bent to drink the water, it drained below the level he could reach, and if he reached for the fruit, the branches moved out of his grasp. It is also found in Australia, Russia and Nigeria. Tantalum was discovered by Anders Gustaf Ekeberg (SE) in 1802. [30], Tantalates, compounds containing [TaO4]3− or [TaO3]− are numerous. It is present in abundance at the core or center of the earth. The metal is renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia. Applications. Ekeberg discovered tantalum in 1802, while he … He embarked on a teaching career at Uppsala where he presented chemical expositions and analysed minerals. Chaussée de Louvain 490, 1380 Lasne, Belgium, AISBL under Belgian law Osmium: Discovered in 1803 by Smithson Tennent 77. [62], Tantalum is inert against most acids except hydrofluoric acid and hot sulfuric acid, and hot alkaline solutions also cause tantalum to corrode. Tantalum exists in two crystalline phases, alpha and beta. The differences between tantalum and niobium were demonstrated unequivocally in 1864 by Christian Wilhelm Blomstrand,[13] and Henri Etienne Sainte-Claire Deville, as well as by Louis J. Troost, who determined the empirical formulas of some of their compounds in 1865. Due to its high density, shaped charge and explosively formed penetrator liners have been constructed from tantalum. And in any case, tantalum appears to be present in natural waters mostly as particulate matter rather than dissolved. It exists in combination with niobium, that is quite similar to tantalum in various characteristics. Tantalum carbide, TaC, like the more commonly used tungsten carbide, is a hard ceramic that is used in cutting tools. [77], People can be exposed to tantalum in the workplace by breathing it in, skin contact, or eye contact. Interesting Facts About Tantalum – 2. iron, manganese, titanium, zirconium), which remain in the aqueous phase in the form of their fluorides and other complexes. K2[TaF7] can be converted to metallic tantalum by reduction with sodium, at approximately 800 °C in molten salt.[56]. Tantalum was discovered in Ytterby, Sweden. [76] Tantalum appears to be a very conservative element in biogeochemical terms, but its cycling and reactivity are still not fully understood. In 1809, William Hyde Wollaston, a British chemist, analysed both columbite and tantalite mineral specimens and claimed that columbium and tantalum were the same element. After graduation from the University of Uppsala (1788) and travels in Germany, Ekeberg returned to Uppsala and began teaching (1794), introducing the chemistry of Antoine-Laurent Lavoisier. Common Uses 73. There are many species of tantalum minerals, only some of which are so far being used by industry as raw materials: tantalite (a series consisting of tantalite-(Fe), tantalite-(Mn) and tantalite-(Mg)) microlite (now a group name), wodginite, euxenite (actually euxenite-(Y)), and polycrase (actually polycrase-(Y)). Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Lithium tantalate (LiTaO3) adopts a perovskite structure. It was discovered in 1802 by Swedish chemist Anders Ekeberg (1767–1813). One mineral he investigated became known as yttrotantalite, from Ytterby, Sweden, and another was from Kimito, Finland. Tantalum is a chemical element with symbol Ta and atomic number 73 in the periodic table. After [74] Analysis requires pre-concentration procedures that, for the moment, do not give consistent results. Tantalum is dark (blue-gray),[21] dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The chemical properties of Ta and Nb are very similar. Heat exchanging coils for the steam heating of hydrochloric acid are made from tantalum. The Distribution of Tantalum Resources in the World [54] Extraction begins with leaching the ore with hydrofluoric acid together with sulfuric acid or hydrochloric acid. Ekeberg had been passionate about ancient Greek literature since childhood and he called it tantalum after Tantalus, the son of Jupiter, who was condemned to eternal frustration and could not drink even though he was standing in water up to his neck. Tantalum was discovered by Anders Gustaf Ekenberg, a Swedish chemist, in 1802 in minerals obtained from Ytterby, Sweden. Tantalum: Discovered in 1802 by Anders Gustav Ekeberg 74. It was not until 1949 that the International Union of Pure and Applied Chemistry (IUPAC) officially adopted niobium as the name for this element. from Audemars Piguet, F.P. [38] Wodgina produces a primary tantalum concentrate which is further upgraded at the Greenbushes operation before being sold to customers. Niobium was discovered in 1802 by Anders Gustaf Ekeberg, but many chemists thought niobium and tantalum were one and the same. The first person to discover tantalum was a man named Anders G. Ekeberg. Applications. The slag from the tin smelters then contains economically useful amounts of tantalum, which is leached from the slag. Tantalum's high melting point of 3017 °C (boiling point 5458 °C) is exceeded among the elements only by tungsten, rhenium and osmium for metals, and carbon. Tantalum is a chemical element with the symbol Ta and atomic number 73. Compounds containing tantalum are rarely encountered in the laboratory. The refining of tantalum from its ores is one of the more demanding separation processes in industrial metallurgy. Closely associated with niobium in ores and in properties, tantalum was discovered (1802) by the Swedish chemist Anders Gustaf Ekeberg and named after the mythological character Tantalus because of the tantalizing problem of dissolving the oxide in acids. An external shell of 181Ta would be irradiated by the intensive high-energy neutron flux from a hypothetical exploding nuclear weapon. This conclusion was disputed in 1846 by the German chemist Heinrich Rose, who argued that there were two additional elements in the tantalite sample, and he named them after the children of Tantalus: niobium (from Niobe, the goddess of tears), and pelopium (from Pelops). Unfortunately for Ekeberg, in 1809 the well-known English chemist Willian Wollaston said there had been no discovery and there was no new element. Tantalum pentafluoride (TaF5) is a white solid with a melting point of 97.0 °C. In aqueous media, Ta only exhibit the +V oxidation state. Ethical questions have been raised about responsible corporate behavior, human rights, and endangering wildlife, due to the exploitation of resources such as coltan in the armed conflict regions of the Congo Basin. Tantalum is a shiny, silvery metal which is soft when is pure. Common Uses The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 5 mg/m3 over an 8-hour workday and a short-term limit of 10 mg/m3. Since it resists attack by body fluids and is nonirritating, tantalum is widely used in making surgical instruments and implants. This property makes it a useful metal for chemical reaction vessels and pipes for corrosive liquids.
