Yttrium(III) sulfate is an inorganic compound with the formula Y2(SO4)3. The most common form is the anhydrate and octahydrate.


Yttrium sulfate can form double salts such as MY(SO4)2[1][2][3] and M3Y(SO4)3:[4][5][6]

Y2(SO4)3 + M2SO4 → 2 MY(SO4)2
Y2(SO4)3 + 3 M2SO4 → 2 M3Y(SO4)3 (M=alkali metals)


Yttrium(III) sulfate can be prepared using either corresponding oxide, hydroxide or carbonate.

2 Y(OH)3 + 3 H2SO4 → Y2(SO4)3 + 6 H2O[7]
