Infobox references

Neodymium(III) sulfate is a salt of the rare earth metal neodymium when mixed with sulfuric acid. Its octahydrate forms violet-red crystals. It is moderately soluble in water and has a monoclinic crystal structure. It can be used to treat water but because of its rarity, it is not used that way.

Preparation[]

Neodymium sulfate is produced by dissolving neodymium metal in sulfuric acid.^[2]

Uses[]

It is used in glass for extremely powerful lasers. It can be used to treat water but is not used because of its rarity.
