About Germanium

Germanium is one of the relatively newly discovered and a bit rare chemical elements. It was named after the Latin word for Germany. It is a light grey metalloid and a semi-conductor, which was used for producing early transistors. In its properties, germanium is quite similar to tin. The pure element can be extracted from a few ores, which are also quite rare. Germanium is used for producing lenses for microscopes and cameras. Its alloys are also used for producing lamps, infrared lamps, etc.

Uses of Germanium

Germanium, grayish-white semi-metallic element with the symbol Ge, is used mostly for fiber-optics, infrared optics, electronics, solar cells, chemotherapy, metallurgy, etc. It is used as a semiconductor and a catalyst. Germanium is employed to alloy with arsenic, zinc or other elements. It is used as an alloying agent in phosphors for fluorescent lamps. Germanium dioxide, an alloy of germanium and oxygen with the chemical formula GeO2, is used in optical microscope objective lenses as well as in algaculture. Germanium tetrachloride is mainly used in the production of purified germanium metal.
