Germanium Information

Germanium is a lustrous hard metalloid element, belongs to group 14 of the periodic table. It forms a large number of organometallic compounds. Predicted by Mendeleev in 1870, germanium was actually found in 1886 by Winkler. Germanium has 33 isotopes. 5 of them are naturally occurring, 4 of which are stable.

Germanium is widely used in semiconductors. It is a good semiconductor when combined with tiny amounts of phosphorus, arsenic, gallium, and antimony.
