'S e meataloighd a tha ann. Tha feartan an gearmainium eadar feartan nam meatailtean agus feartan nam neo-mheatailtean.

Eachdraidh

Ann an 1869, ro-innis Dmitri Mendeleev a bhith na h-eileamaid a dh'ainmich e eka-silicon.[2]Ann an 1886 rinn Clemens Winkler gearmainium fìorghlan. Lorg e gearmainium ann am mèinnear argarodaid (Ag8GeS6).

Cleachdadh

Cleachdar gearmainium ann an radharc-eòlas agus ann an catalais.
