Zirconium(IV) sulfate


Zirconium sulfate is the name for a family of inorganic compounds with the formula Zr2n where n = 0, 4, 5, or 7. These species are related by the degree of hydration. At least some members of the series contain oxo ligands since zirconyl is pervasive. These compounds are white or colorless solids that often are soluble in water.

Preparation and structure

Zirconium sulfate is prepared by the action of sulfuric acid on zirconium oxide:
The anhydrous sulfate is also claimed.
These compounds adopt complex structures featuring 7- and 8-coordinated Zr centres. Both water and sulfate serve as ligands.

Uses

Zirconium sulfate is used in tanning white leather, as a catalyst support, to precipitate proteins and amino acids, and as a pigment stabilizer.
