'''硫酸铵'''，简称'''硫铵'''，又稱'''硫酸錏'''，[[化学式]]為{{化學式|銨|2|S|O|4}}，无色斜方晶体，易溶于水，水溶液為酸性。

==用途==
硫酸铵是一种[[氮肥]]，但对强酸性土壤须同[[石灰]]配合施用，在石灰性反应强的土壤上，须深施覆土，以减少氮的损失；也可用作[[焊药]]及织物[[防火剂]]。

==製備==
硫酸铵可以在[[硫酸]]中直接通入[[氨]]制得。

<chem>2NH3 + H2SO4 -> (NH4)2SO4</chem>

由[[一水合氨]]和硫酸中和后，结晶、离心分离并干燥而得。中和法氨与硫酸约在100℃下进行中和反应，生成的硫酸铵晶浆液经离心分离、干燥，制得硫酸铵成品。

<chem>2NH3*H2O + H2SO4 -> (NH4)2SO4 + 2H2O</chem>

其回收法由炼焦炉气回收氨气，再与硫酸进行中和反应而得。<ref>{{Cite web |url=http://china.guidechem.com/15561/ |title=硫酸铵-盖德化工网 |accessdate=2011-12-13 |archive-date=2011-12-03 |archive-url=https://web.archive.org/web/20111203062553/http://china.guidechem.com/15561 |dead-url=no }}</ref>
