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