Product Code : ME-Ge-7N-CU
Pure germanium is a kind of gray white metal, glossy, hard, belonging to the carbon group. Its chemical properties are similar to those of tin and silicon in the same group. It is insoluble in water, hydrochloric acid, dilute caustic solution, aqua regia, concentrated nitric acid or sulfuric acid. It is also stable in air. Germanium is amphoteric, so it is soluble in molten alkali, peroxide alkali, alkali metal nitrate or carbonate. Germanium metal is a semiconductor, mainly used in transistors, integrated circuits and various other electronic devices. Germanium's major end uses are in fiber-optic systems, infrared optics and in solar cell applications.High-purity germanium is a semiconductor material. It can be obtained by reduction of high-purity germanium oxide and smelting. Germanium single crystal doped with a small amount of specific impurities can be used to make various transistors, rectifiers and other devices. Germanium compounds are used in the manufacture of fluorescent plates and various high refractive index glasses. ATT is a professional supplier of high-purity germanium metal, in the forms of lumps, chucks, ingots, blocks and beads. The purity levels are 99.9% (3N), 99.99% (4N),99.999% (5N) , 99.9999% (6N). 99.99999% (7N)

Applications of Germanium Metal
Germanium has many special properties. It is an important strategic resource and has wide-range and important applications in semiconductor, aerospace measurement and control, nuclear physics detection, optical fiber communication, infrared optics, as well as solar cells, chemical catalysts, biomedicine, and other fields. In the electronic industry, alloy pretreatment, and the optical industry, it can also be used as a catalyst.
Germanium Metal is used to manufacture rectifiers, transistors, and weapons-sighting systems and is used as a fluorescent material. Alloying agent. It can also be used as a catalyst to produce plastics.Germanium single crystal is used as the first generation transistor material. Germanium is used in radiation detectors and thermoelectric materials. High-purity germanium single crystal has high refractive index. It is only transparent to infrared light, but opaque to visible light and ultraviolet light. So it can be used as a germanium window, prism or lens for infrared light transmission. The infrared night vision instruments and other military observation instruments also use pure germanium to make lens.
In addition, germanium compounds also have a wide range of applications. Germanium and niobium compounds are superconducting materials. Germanium dioxide is a catalyst for polymerization. The glass containing germanium dioxide has high refractive index and dispersion properties, and can be used as a wide-angle camera and microscope lens. Germanium trichloride is also a new type of optical fiber material additive.
