Germanium is a chemical element, its chemical symbol is Ge, atomic number is 32, atomic weight is 72.64. It is located in the fourth cycle and IVA group in the periodic table of chemical elements. Germanium is a kind of gray white quasi metal, lustrous, hard, belonging to the carbon group. Its chemical properties are similar to those of tin and silicon of the same group. It is insoluble in water, hydrochloric acid, dilute caustic solution, aqua regia, concentrated nitric acid or sulfuric acid. It is amphoteric. Therefore, it is soluble in molten alkali, peroxide alkali, alkali metal salt or acid salt. It is stable in the air. In nature, there are five kinds of germanium isotopes: 70 Germanium is an excellent semiconductor, which can be used for detecting high frequency current and rectifying alternating current. In addition, it can be used as infrared light material, precision instrument and catalyst. Germanium compounds can be used to make fluorescent plates and glasses with high refractive index
