It is a very important semiconductor material. 5 years ago. Germanium is not thought to be an essential element for any living organism. Germanium metal is a shiny silvery metalloid and a semiconductor. [75], Germanium-on-insulator (GeOI) substrates are seen as a potential replacement for silicon on miniaturized chips. The world's largest producer of refined Germanium is China, which accounts for about 70 percent of the over 150 metric tonnes produced worldwide each year. A more recent organic form, beta-carboxyethylgermanium sesquioxide (propagermanium), has not exhibited the same spectrum of toxic effects. However, it is difficult and expensive to make large crystals with sufficient purity. Fast ausverkauft. Germanium metal is a semimetal of light gray with a metallic sheen. It is used as an intermediate in the production of purified germanium metal. [78] The high brilliance of this polyester is especially favored for PET bottles marketed in Japan. Germanium is the substrate of the wafers for high-efficiency multijunction photovoltaic cells for space applications. [23] These end uses represented 85% of worldwide germanium consumption in 2000. RE: Is Germanium a metal element??? Moreover, germanium has lower average energy necessary to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium. The first metallic material discovered (in 2005) to become a superconductor in the presence of an extremely strong electromagnetic field was an alloy of germanium, uranium, and rhodium.[33]. Technically, germanium is classified as a metalloid or semi-metal. eV This is primarily because it usually occurs only as a trace element in ores and carbonaceous materials, and the various industrial and electronic applications involve very small quantities that are not likely to be ingested. [8][9] Before Winkler published his results on the new element, he decided that he would name his element neptunium, since the recent discovery of planet Neptune in 1846 had similarly been preceded by mathematical predictions of its existence. Germanium and its oxide are transparent to infrared light. A large, clean and almost perfect germanium semiconductor is ideal as a counter for radioactivity. The latter makes Germanium metal an important material in electronics and solar technology. Circuits utilizing the properties of Si-SiGe junctions can be much faster than those using silicon alone. Hochreine Germaniummetallbarren werden am häufigsten durch Aufbereitung von Germaniumdioxid (GeO2) über einen Zonenveredelungsprozess hergestellt. [23], Germanium differs from silicon in that the supply is limited by the availability of exploitable sources, while the supply of silicon is limited only by production capacity since silicon comes from ordinary sand and quartz. [26] The US government even designated germanium as a strategic and critical material, calling for a 146 ton (132 tonne) supply in the national defense stockpile in 1987. Ganz anders sieht es deshalb mit Germanium in Heilwässern, wie etwa den berühmten Quellen von Lourdes oder Fatima, aus oder mit Germanium in Heilpflanzen und Heilpilzen. freezes) from the molten state. Germanium is a metalloid. In 1869, Dmitri Mendeleev predicted its existence and some of its properties from its position on his periodic table, and called the element ekasilicon. Zone refining techniques allow for the production of ultra-pure germanium. Sometimes organic Germanium compounds are sold as obscure miracle cures. EUR 19,90 + Versand . [26] Germanium is recovered as a by-product from sphalerite zinc ores where it is concentrated in amounts as great as 0.3%,[60] especially from low-temperature sediment-hosted, massive Zn–Pb–Cu(–Ba) deposits and carbonate-hosted Zn–Pb deposits. [note 1] The chemist Clemens Winkler analyzed this new mineral, which proved to be a combination of silver, sulfur, and a new element. It conducts an electric current poorly. Germanium has a moderate ionisation energy (762 kJ/mol), moderate electron affinity (119 kJ/mol), and moderate electronegativity (2.01). Similar to silicon and aluminium, naturally-occurring germanium compounds tend to be insoluble in water and thus have little oral toxicity. Germanium gilt, wie so viele Metalle, in vielen Verbin-dungen als giftig und ist deshalb als Nahrungsergänzung in Deutschland verboten. [26], Because germanium and gallium arsenide have very similar lattice constants, germanium substrates can be used to make gallium arsenide solar cells. Harefuah 11-16-1997;133(10):446-7, 502. The most stable of these is 68Ge, decaying by electron capture with a half-life of 270.95 days. [41] By heating the disulfide in a current of hydrogen, the monosulfide (GeS) is formed, which sublimes in thin plates of a dark color and metallic luster, and is soluble in solutions of the caustic alkalis. [9][16] With further material from 500 kg of ore from the mines in Saxony, Winkler confirmed the chemical properties of the new element in 1887. This element forms a large number of organogermanium compounds, such as tetraethylgermanium, useful in organometallic chemistry. Germanium metal is a shiny silvery metalloid and a semiconductor. People use it as medicine. Its unique properties, however, make it much more valuable than other metals that were being used at this time. About Titanium germanium bracelet. [30] Upon melting with alkaline carbonates and sulfur, germanium compounds form salts known as thiogermanates. [88], U.S. Food and Drug Administration research has concluded that inorganic germanium, when used as a nutritional supplement, "presents potential human health hazard". A crystal lattice is a repeating pattern of mathematical points that extends throughout space. After removing some of the zinc in the precipitate by the Waelz process, the residing Waelz oxide is leached a second time. Ein Recyling besteht nur in beschränktem Mass. Overview Information Germanium is a chemical element. [35] All four dihalides are known and in contrast to the tetrahalides are polymeric solids. Germanium itself is classified as a metalloid. It is a poor oxidising agent (Ge + 4e → GeH 4 = –0.294 at pH 0). There have been more … Versand: + EUR 2,99 Versand . EUR 4,49. It can occasionally be found in copper ores. Uses: Germanium is an important semiconductor material. It also is a semiconductor, which means it has electrical conductivity between an insulator and a conductor. Bewertungen filtern sehr gut gut befriedigend ausreichend mangelhaft. Today, germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores. Become a Study.com member to unlock this In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. [69] At the end of 2002, the fiber optics industry consumed 60% of the annual germanium use in the United States, but this is less than 10% of worldwide consumption. 16 Nov 2020 by Evan Griffith | View Bio. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. [35] Other oxidation states are rare: +3 is found in compounds such as Ge2Cl6, and +3 and +1 are found on the surface of oxides,[36] or negative oxidation states in germanides, such as −4 in Mg2Ge. Germanium is located in the middle of the carbon family, which is Group 14 (IVA) in the periodic table. Germanium is mainly a byproduct of zinc ore processing. [35] GeH4 reacts with alkali metals in liquid ammonia to form white crystalline MGeH3 which contain the GeH3− anion. [76] Other uses in electronics include phosphors in fluorescent lamps[31] and solid-state light-emitting diodes (LEDs). Field. [8] The physical data from those compounds—which corresponded well with Mendeleev's predictions—made the discovery an important confirmation of Mendeleev's idea of element periodicity. [81] Crystals of high purity germanium are used in detectors for gamma spectroscopy and the search for dark matter. Under standard conditions, germanium is a brittle, silvery-white, semi-metallic element. [30], Germanium is a semiconductor. making it one of the purest materials ever obtained. EUR 6,95 + Versand .
