Babban-tsarki germanium abu ne na semiconductor.Ana iya samun shi ta hanyar raguwa daga babban germanium oxide mai tsabta da narkewa.Za'a iya amfani da kristal guda ɗaya na germanium wanda aka ɗora tare da takamaiman ƙazanta don yin transistor, masu gyara da sauran na'urori.Ana amfani da mahadi na Germanium don yin faranti mai kyalli da tabarau daban-daban masu girman kai.

Germanium yana aiki don murkushe lalacewar da radiation ta haifar, ta haka ne ya rage lalacewa da kuma dawo da ƙwayoyin da suka ji rauni.Ƙara yawan jini ta hanyar ƙwayoyin jini don tsaftace jini.Ciwon daji na hanta.Maganin ciwon daji na huhu, ciwon ciki da sauran cututtukan daji masu wadatar jijiyoyin jini da cututtukan numfashi, asma da cututtukan fata da sauran cututtuka na da tasiri na musamman.
