Germanium - Wikipedia

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.


Mar 01, 2004· Similarly, germanium must compete with gallium, indium, and rare earth metals in a very selective industry. Niobium and tantalum are sometimes substituted for these metals. The predominant minerals hosting germanium include argyrodite, germanite, and renierite while lead/zinc deposits plus certain coals represent another major source of supply.
