Zirconium Hydroxide
Zirconium (IV) hydroxide, often called hydrous zirconia is an ill-defined material or family of materials variously described as {displaystyle {\ce {ZrO2.{mathit {n}}H2O}}} and {displaystyle {\ce {Zr(OH)4.{mathit {n}}H2O}}}. All are white solids with low solubility in water. These materials are widely employed in the preparation of solid acid catalysts.[1][2]
These materials are generated by mild base hydrolysis of zirconium halides and nitrates. A typical precursor is zirconium oxychloride
