who discovered germanium

[p.223] A third element that Mendeléeff had predicted was to be a member of the silicon family. He suggested therefore the name ekasilicon (symbol Es). Common names include germanium-132 (Ge-132) and germanium sesquioxide. Germanium is a rare, silver-colored semiconductor metal that is used in infrared technology, fiber optic cables, and solar cells. He named it eka-silicon and proposed some of the physical characteristics of the then unknown metal. at Bell Laboratories [20] were the first to develop a working silicon transistor on January 26, 1954. Germanium is a silvery white metalloid. Germanium belongs to the carbon family and used in electronic devices as semiconductors. [21] This is a 2-by-3 centimeter piece of polycrystalline germanium, weighing about 12 grams. A 2012 study examined changes in rat fecal bacteria and found no correlation that Ge-132 accumulated in … Germanium was discovered in a mineral called argyrodite by Clemens Alexander Winkler in 1886. 1886: Chemist Clemens A. Winkler discovered and isolated the element germanium from the rare mineral argyrodite (Ag8GeS6). Germanium was also discovered in a mineral called argyrodite by Clemens Alexander Winkler in 1886. About Germanium Clemens Winkler Journal für praktische Chemie 142 (N. F. 34) (1886), pp. In 1886, German chemist named Clemens A. Winkler successfully discovered germanium in the mineral sample from the silver mine. Analysis indicated the sample contained 73 – 75% silver, 17 – 18% sulfur, 0.2% mercury, and 6 – 7% a new element. While today germanium is considered a valuable semiconductor, when it was originally discovered, it was believed to a weakly conducting metal without much use. The name of Germanium comes from the Latin word Germania, which means Germany. Germanium is a metalloid element. Germanium was discovered in 1886. His predictions for the properties of germanium are remarkably close to the reality. ... Seventeen years later chemist Clemens A. Winkler discovered and isolated the element from the rare mineral argyrodite (Ag8GeS6). He … Morris Tanenbaum et al. Clemens Winkler discovered Germanium in 1886 in Germany. Scientists theorized that silicon would be easier to fabricate, but few bothered to investigate this possibility. 177-229. By its appearance alone it was beyond question that argyrodite was a sulpho salt. This “ekasilicon was discovered in 1886 by Clemens Winkler, who named it germanium in honor of his fatherland. He predicted that the then unknown element germanium should resemble silicon in its properties. He then analyzed that his mineral sample, known as argyrodite, consisted of 73-75 % silver, 17-18 % sulfur, 0.2% mercury and 6-7% new element. He named the element after his homeland, Germany. 1 Today, germanium’s excellent electronic properties are exploited, as there is a growing demand for faster computers, higher efficiency photovoltaics, and more sensitive detectors. History and Discovery. Dmitri Mendeleev predicted the existence of germanium in 1869. He discovered the element germanium and made pioneer researches on indium. Germanium was difficult to purify, and had a limited operational temperature range. Germanium is created through stellar nucleosynthesis, mostly by the s-process in asymptotic giant branch stars.
