Germanium is a chemical element, chemical symbol Ge, atomic number 32, atomic weight 72.64, belong to IVA family elements. The melting point is 937.4 degrees, the boiling point is 2830 degrees, the density is 5.35g/cm, the hardness is 6 ~ 6.5. Germanium is a greyish white metal with luster and hard quality. It belongs to the carbon family and has obvious non-metallic properties. Germanium is chemically stable and does not react with air or water vapor at room temperature. However, germanium dioxide can be rapidly formed at 600-700 C. Germanium content in the earth's crust is about 0.0007%. It is one of the most dispersed elements in the earth's crust. A large amount of germanium is distributed in a dispersed state in all kinds of metal silicate, sulfide ore and various types of coal; some copper ore, iron ore, sulfide ore and silver ore also have germanium; rocks, soil, and springs contain trace germanium; many plants contain limited germanium, such as three, three party, dahurian dahuri, Wolfman. Qi, aloe, ganoderma and tea and so on. Germanium is widely used in electronics, optics, chemical industry, biomedicine, energy and other high and new technology fields.
