在生產[[聚對苯二甲酸乙二酯]]的過程中，二氧化鍺還可以用於[[催化劑|催化]][[聚合]]作用<ref name=Thiele>{{cite journal | last = Thiele | first = Ulrich K. | year = 2001 | title = The Current Status of Catalysis and Catalyst Development for the Industrial Process of Poly(ethylene terephthalate) Polycondensation | journal = International Journal of Polymeric Materials | volume = 50 | issue = 3 | pages = 387 – 394 |doi = 10.1080/00914030108035115  }}</ref>。這樣生產出來的成品耀度很高，所以在[[日本]]銷售的PET瓶子都專門選用這一種[[聚酯]]<ref name=Thiele/>。然而，美國不把鍺用作聚合催化劑<ref name=usgs/>。由於[[二氧化硅]]與二氧化鍺相近，所以[[氣相色譜法|氣相色譜]]柱中的固定[[相態|相]]二氧化硅，可用二氧化鍺來取代<ref>{{cite journal | title = Germania-Based, Sol-Gel Hybrid Organic-Inorganic Coatings for Capillary Microextraction and Gas Chromatography | last=  Fang| first=Li | last2 =Kulkarni|first2=Sameer|last3=Alhooshani|first3=Khalid|last4=Malik|first4=Abdul | journal = Anal.

近年，在[[貴金屬]]合金中加入鍺是愈來愈多。例如，在[[英幣標準銀]]（sterling silver）（含銀量達95%以上的合金）中加入鍺，就能減少[[火紋]]（firescale）、增加抗[[鏽色]]性（tarnish）及增加對[[析出硬化]]（precipitation hardening）的反應。有一種抗鏽色的銀合金，商標名叫Argentium，其含鍺量需達1.2%<ref name=usgs/>。

高純度鍺單晶探測器，能準確地探測出輻射的來源，因此可用於機場保安系統<ref>{{cite web|title=Performance of Light-Weight, Battery-Operated, High Purity Germanium Detectors for Field Use |first=Ronald |last=Keyser |last2=Twomey|first2=Timothy|last3=Upp|first3=Daniel |url=http://www.ortec-online.com/papers/inmm_2003_keyser.pdf |format=pdf |accessdate=2008-09-06 |publisher=Oak Ridge Technical Enterprise Corporation (ORTEC) |deadurl=yes |archiveurl=https://web.archive.org/web/20071026162911/http://www.ortec-online.com/papers/inmm_2003_keyser.pdf |archivedate=2007-10-26 }}</ref>。鍺亦被用於[[晶體單光儀]]（crystal monochromator），這台儀器能生成[[單晶材料|單晶]][[中子散射]]（neutron scattering）及[[同步輻射|同步X射線]]繞射所需的線性束。在中子及高能[[X射線]]的應用，鍺的反射性比硅優勝<ref>{{cite journal |doi=10.1142/S0218301396000062 |year=1996 |author=Ahmed, F.

鍺的一些化合物對[[哺乳類]]動物沒甚麼毒性，可是對某些[[細菌]]則有着相當的毒性<ref name="nbb">{{cite book| last = Emsley| first = John| title = Nature's Building Blocks| publisher = Oxford University Press| date = 2001| location = Oxford| pages = 506–510| isbn = 0-19-850341-5 }}</ref>。就因為這項特性，所以這些鍺化合物可用作[[化學治療]]劑<ref>{{cite journal | first = Milan | last = Slavik | last2 = Blanc|first2=Oscar|last3=Davis|first3=Joan | title = Spirogermanium: A new investigational drug of novel structure and lack of bone marrow toxicity | journal = Investigational New Drugs | volume = 1 | issue = 3 | year = 1983 | doi = 10.1007/BF00208894 | pages = 225–234}}</ref>。
