锗是一种呈银灰色的新兴金属,于1886年被德国人温克列尔首次发现.锗在地壳内分布极广,含量为0.00067%.它主要以硫化物形式存在,或与其它元素,特到是铜、锌、铅、锡及锑的硫化矿伴生.除从金属矿物中获锗之外,煤亦是提取锗的另一潜在来源,煤中的有机物富集有锗.锗在土壤中为谷物所吸收、特别是燕麦的吸收力更强.德国的橡树和山毛榉腐植质中含锗达0.007%之多. Germanium is a silver-colored emerging metal first discovered by the German Winkelle in 1886. Ge is widely distributed in the earth’s crust at a content of 0.00067%, mainly in the form of sulphides or with other elements, In particular, copper, zinc, lead, tin and antimony sulfide sulfide associated with.In addition to obtaining germanium from the metal minerals, coal is also another potential source of extracted germanium, organic matter rich in germanium.Ge germanium in the soil In the absorption of grains, especially the absorption of oats stronger German oak and beech humus containing Germanium up to 0.007%.
