Indium Corporation
Indium Corporation is a materials refiner, Smelting, smelter, manufacturer, and supplier to the global electronics, semiconductor, thin-film, and thermal management markets. Products include solders and Flux (metallurgy), fluxes; Brazing, brazes; thermal interface materials; sputtering targets; indium, gallium, germanium, and tin metals and inorganic compounds; and NanoFoil. Founded in 1934 in Utica, New York, the company has global technical support and factories located in China, Germany, India, Malaysia, Singapore, South Korea, the United Kingdom, and the United States, U.S. History In 1863, the element indium was discovered by Professor Ferdinand Reich (1799–1882) and his assistant Hieronymous Theodor Richter (1824–1898) while at the Technical University of Bergakademie Freiberg, Freiberg University of Mining and Technology, Germany. Reich, who was Color blindness, color blind, asked Richter to examine a yellow precipitate from some local zinc ores. Spectroscopy, Spectro ...

Electronics
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other Electric charge, electrically charged particles. It is a subfield of physics and electrical engineering which uses Passivity (engineering), active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signal, analog signals to digital signal, digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in respo ...

Gallium
Gallium is a chemical element; it has Chemical symbol, symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, elemental gallium is a soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white. If enough force is applied, solid gallium may fracture conchoidal fracture, conchoidally. Since its discovery in 1875, gallium has widely been used to make alloys with low melting points. It is also used in semiconductors, as a dopant in semiconductor substrates. The melting point of gallium, , is used as a temperature reference point. Gallium alloys are used in thermometers as a non-toxic and environmentally friendly alternative to Mercury (element), mercury, and can withstand higher temperatures than mercury. A melting point of , well below the freezing point of water, is claimed for the alloy galinstan (62–95% gallium, 5–22% indium, and 0–16% tin by weight), but that may be t ...

Hieronymous Theodor Richter
Hieronymus Theodor Richter (21 November 1824 – 25 September 1898) was a German chemist. In 1863, while working at the Freiberg University of Mining and Technology, he co-discovered indium with Ferdinand Reich. Life From 1843 to 1847, he studied at the Bergakademie Freiberg (with Carl Friedrich Plattner, among others) and became a member of the Corps Saxo-Borussia Freiberg. He then worked for the Freiberg Hüttenwerken, since 1853 as a metallurgist chemist. From 1875 to 1896, Theodor Richter worked as director of the Mining Academy and was the last of the Freiberg directors elected for lifetime. In 1890 he was elected a member of the Leopoldina. He died September 25, 1898, in Freiberg, Saxony Freiberg () is a college town, university and former mining town in Saxony, Germany, with around 41,000 inhabitants. The city lies in the foreland of the Ore Mountains, in the Saxon urbanization axis, which runs along the northern edge of the ..., at the age of 73. Honours In 1 ...

Ferdinand Reich
Ferdinand Reich (19 February 1799 – 27 April 1882) was a German chemist who co-discovered indium in 1863 with Hieronymous Theodor Richter. Reich was born in Bernburg, Anhalt-Bernburg, Holy Roman Empire and died in Freiberg, Saxony, Freiberg. He was color blindness, color blind, or could only see in whites and blacks, and that is why Theodor Richter became his science partner. Richter would examine the colors produced in reactions that they studied. Reich and Richter ended up isolating the indium, creating a small supply, although it was later found in more regions. They isolated the indium at the Technische Universität Bergakademie Freiberg, Freiberg University of Mining and Technology in Germany. In 1803, Laplace and Gauss both derived that, if a heavy object is dropped from a height h at latitude \Phi, and the earth rotates from west to east with angular velocity \Omega, then the object would be deflected to the east by a distance of d=2 / 3 \Omega \cos (\Phi) \sqrt ...

Indium Ore
Indium is a chemical element; it has symbol In and atomic number 49. It is a silvery-white post-transition metal and one of the softest elements. Chemically, indium is similar to gallium and thallium, and its properties are largely intermediate between the two. It was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods and named for the indigo blue line in its spectrum. Indium is used primarily in the production of flat-panel displays as indium tin oxide (ITO), a transparent and conductive coating applied to glass. It is also used in the semiconductor industry, in low-melting-point metal alloys such as solders and soft-metal high-vacuum seals. It is produced exclusively as a by-product during the processing of the ores of other metals, chiefly from sphalerite and other zinc sulfide ores. Indium has no biological role and its compounds are toxic when inhaled or injected into the bloodstream, although they are poorly absorbed following ...
