It is also used in infrared spectroscopes and infrared detectors. Germanium Dietary Supplement. This element is amazing as it raises the level of activity of various organs by enabling them to attract more oxygen. Germanium is also used in airport scanners, as it can often detect radiation. Germanium catalysts are used primarily in the production of plastics. Germanium is LIKELY UNSAFE when taken by mouth in elemental form and in the form of certain compounds such as germanium oxide and germanium lactate-citrate. The following uses for germanium are gathered from a number of sources as well as from anecdotal comments. GERMANIUM-70 isotope is used for Arsenic-72 (As-72 isotope, 72As isotope) radionuclide (radioisotope) production (can be used in life science for healthcare and medical applications and pharmaceuticals industries); I'm working on a PhD, essentially focusing on fabricating and utilizing germanium diodes. Germanium is used to make nanowires, which is one of its most recent usages. Germanium has been used to treat depression, arthritis, vision problems, elevated blood pressure, heavy metal poisoning, and cancer. Silicon germanium (SiGe) is now a popular semiconductor that has skyrocketed in its production since the 90s. Germanium is necessary for the optimum nutrition of the human body. Germanium ore are veins of germanium oxide embedded in basalt rock. Uses of Germanium. Germanium acts as a semiconductor, commonly doped with arsenic and other elements and used as a transistor in different electronic applications. Germanium-based semiconductor detectors are most commonly used where a very good energy resolution is required, especially for gamma spectroscopy, as well as x-ray spectroscopy. A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a silicon-silicon-germanium alloy is commonly used to increase transmission speed of electrical signals. Fiber optics and infrared cameras still account for a huge amount of modern day uses for germanium. Germanium is also an effective alloying agent – for example, using 1 percent germanium in silver stops tarnishing. The inorganic mineral is basically used in the electronics sector as a semiconductor of electricity. Semiconductors Because germanium has traits that are similar to silicon and tin, the semiconductor industry uses germanium on a regular basis.
