===其它用处===
镓可用于探测[[中微子]]。可能是有史以来有最多纯镓的地方是俄罗斯巴克三中微子观测所在{{le|俄美鎵實驗|SAGE (Soviet-American Gallium Experiment)}}中所使用的镓-锗中微子望远镜。这个探测器含有55–57吨（~9立方米）的液镓。<ref>{{cite web|url= http://ewi.npl.washington.edu/sage/|title= Russian American Gallium Experiment|date= 2001-10-19|access-date= 2009-06-24|archive-url= https://web.archive.org/web/20100705232418/http://ewi.npl.washington.edu/SAGE/|archive-date= 2010-07-05|url-status= dead}}</ref>另一个实验是1990年代初在意大利山区隧道中运行的{{le|GALLEX}}中微子探测器，探测器中装有12.2吨加水的镓-71。太阳中微子会使几个原子的<sup>71</sup>Ga变成放射性的<sup>71</sup>[[锗|Ge]]，而后者会被检测到。该实验表明，太阳中微子通量比理论预测少40%。在构建更好的太阳中微子探测器和理论之前，这种缺陷没有得到解释（参见[[萨德伯里中微子观测站|SNO]]）。<ref>{{cite web|url= http://wwwlapp.in2p3.fr/neutrinos/anexp.html#gallex|title= Neutrino Detectors Experiments: GALLEX|date= 1999-06-26|access-date= 2008-11-20|archive-date= 2010-04-14|archive-url= https://web.archive.org/web/20100414111001/http://wwwlapp.in2p3.fr/neutrinos/anexp.html#gallex}}</ref>

镓还用作[[聚焦离子束]]的{{le|液态金属离子源|Liquid metal ion source}}。镓离子聚焦束创造了世界上最小的书——《{{le|芜菁镇的小泰德|Teeny Ted from Turnip Town}}》。<ref name="pr">[https://www.sfu.ca/mediapr/news_releases/archives/news04110701.htm "Nano lab produces world's smallest book"] {{Wayback|url=https://www.sfu.ca/mediapr/news_releases/archives/news04110701.htm |date=20151013010453 }}.

由于镓的外观类似它较轻的同类物铝，化学家之间著名的[[恶作剧]]是制作镓汤匙并用它们为毫无戒心的客人提供茶水。这些汤匙会在热茶中融化。<ref name="Sam Kean2010">{{cite book|author=Kean, Sam|title=The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements|url=https://archive.org/details/disappearingspoo0000kean_p8o5|date=2010|publisher=Little, Brown and Company|location=Boston|isbn=978-0-316-05164-4|registration=yes}}</ref>
