Indium

History

Indium is one of the most rare and trace metals, because of that it was open only in the second half of the 19 century. In 1863, German chemists Reich and Richter had spectroscopic analysis of the jack near the town of Freiberg. After spectroscopic analysis, there was found blue line (wavelength 4511 Ǻ), roughly the same, what makes a well-known indigo dye. Such a line was not none of the known elements. The new element was given the name because of its blue color - indium. Until 1870, Indium has a lot of thought to the atomic weight 75.6. But then Mendeleev found that it equals 113. Later it was found that there was a natural indium with a mass 115 isotope, which prevails in the world.   Indium threads cause in some cases of the glass lenses.

Nowadays

Widespread use of Indium began only in the 20 st century. On its own, the metal is very soft: scratches can be made even by fingernail, but in combination with tin, it acquires sufficient strength. This alloy makes bearings for automotive and aircraft engines. Indium used as solders. Use it in the semiconductor industry, where the most concentrated use of indium. Indium threads cause in some cases of the glass lenses.
