Neodymium(III) sulfate is a salt of the rare-earth metal neodymium that has the formula Nd2(SO4)3. It forms multiple hydrates, the octa-, penta-, and the dihydrate, which the octahydrate is the most common. This compound has a retrograde solubility, unlike other compounds, its solubility decreases with increasing temperature.[3] This compound is used in glass for extremely powerful lasers.

## Preparation

Neodymium sulfate is produced by dissolving neodymium(III) oxide in sulfuric acid:

3 \+ 3H
2SO
4 → Nd
2(SO

3 \+ 3H

It can also be prepared by the reaction of neodymium(III) perchlorate and sodium sulfate.

## Properties

Neodymium sulfate octahydrate decomposes at 40 °C to the pentahydrate, which in turn decomposes to the dihydrate at 145 °C. The dihydrate dehydrates to the anhydrous form at 290 °C.[4]
