Infobox references

Zirconium (IV) hydroxide, often called hydrous zirconia is an ill-defined material or family of materials variously described as ZrO
2 * nH
2O and Zr(OH)
4 * nH
2O. All are white solids with low solubility in water. These materials are widely employed in the preparation of solid acid catalysts.[2][3]

These materials are generated by mild base hydrolysis of zirconium halides and nitrates. A typical precursor is zirconium oxychloride.[2]
