====汞齐====
汞容易与大部分普通金属形成[[合金]]，这些汞合金统称[[汞齊]]。能与汞形成合金的金属包括[[金]]和[[银]]，但不包括[[铁]]，所以铁粉一直以来被用于置换汞。其他一些第一行的过渡金属难于形成合金，但不包括[[锰]]、[[铜]]和[[锌]]。其他不易与汞形成合金的元素有[[铂]]<ref>{{cite book|author=Gmelin, Leopold|title=Hand book of chemistry|url=https://books.google.com/books?id=1AI5AAAAMAAJ&pg=PA128|access-date=2012-12-30|date=1852|publisher=Cavendish Society|pages=103 (Na), 110 (W), 122 (Zn), 128 (Fe), 247 (Au), 338 (Pt)|url-status=live|archive-url=https://web.archive.org/web/20130509033751/http://books.google.com/books?id=1AI5AAAAMAAJ&pg=PA128|archive-date=2013-05-09}}</ref><ref>{{cite book|author=Soratur|title=Essentials of Dental Materials|url=https://books.google.com/books?id=N6HbxyaSt78C&pg=PT14|date=2002|publisher=Jaypee Brothers Publishers|isbn=978-81-7179-989-3|page=14|url-status=live|archive-url=https://web.archive.org/web/20160603085942/https://books.google.com/books?id=N6HbxyaSt78C&pg=PT14|archive-date=2016-06-03}}</ref>和其他一些金属。[[钠汞齐]]是有机合成中常用的[[还原剂]]，也被用于[[高压钠灯]]中。

当汞和纯金属[[铝]]接触时，它们易于形成[[铝汞齐]]，因为铝汞齐可以破坏铝表面的[[氧化铝]]层，所以即使很少量的汞也能严重腐蚀金属铝。出于这个原因，绝大多数情况下，汞不能被带上飞机，因为它很容易与飞机上暴露的铝质部件形成合金而造成危险。<ref name="CorrAl">{{cite book |author =Vargel, C. |author2 =Jacques, M. |author3 =Schmidt, M.
