Zirconium(IV) sulfate is the name for a family of inorganic compounds with the formula Zr(SO4)2(H2O)n where n = 0, 4, 5, 7. These species are related by the degree of hydration. They are white or colourless solids that are soluble in water.

Preparation and structure[edit]

Zirconium sulfate is prepared by the action of sulfuric acid on zirconium oxide:

ZrO2 + 2 H2SO4 + H2O → Zr(SO4)2(H2O)x

The anhydrous sulfate is also known.

These compounds adopt complex structures featuring 7- and 8-coordinated Zr centres. Both water and sulfate serve as ligands.[2][3]

Uses[edit]

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