'''硫酸亚铕'''是[[铕]]的一种[[硫酸盐]]，化学式 EuSO<sub>4</sub>。

== 制备 ==
硫酸亚铕可以由[[三氯化铕]][[盐酸]]溶液和[[锌]]和[[硫酸]]反应而成。<ref name="brauer" />

:<math>\mathrm{2 \ EuCl_3 + Zn + 2 \ H_2SO_4 \longrightarrow 2 \ EuSO_4 \downarrow + \ ZnCl_2 + 4 \ HCl}</math>

它也可以由任何一种可溶铕(II)盐和稀硫酸反应而成。<ref>{{cite journal |doi=10.1002/9780470132333.ch19|title=Europium(II) Salts |journal=Inorganic Syntheses |year=1946 |last1=Cooley |first1=Robert A. |last2=Yost |first2=Don M. |pages=69–73 |volume=2}}</ref>

== 性质==
硫酸亚铕是对空气稳定的白色固体，难溶于水。硫酸亚铕在空气中储存几个月后才会被氧化。它的[[晶体结构]]和硫酸锶、硫酸钡一样，都是[[正交晶系]] 的，空间群 Pnma (No. 62)<ref name="brauer" /><ref name="DOI10.1107/S0365110X64002699">{{cite journal | last=Mayer | first=I. | last2=Levy | first2=E. | last3=Glasner | first3=A. | title=The crystal structure of EuSO4and EuCO3 | journal=Acta Crystallographica | publisher=International Union of Crystallography (IUCr) | volume=17 | issue=8 | date=1964-08-01 | issn=0365-110X | doi=10.1107/s0365110x64002699 | pages=1071–1072}}</ref>它有两种同质异形体。<ref name="Jane E.
