Chemical compound

Zirconium (IV) hydroxide, often called hydrous zirconia is: an ill-defined material or family of materials variously described as ZrO₂·nH₂O and Zr(OH)₄·nH₂O. All are white solids with low solubility in water. These materials are widely employed in the: preparation of solid acid catalysts.

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