Zirconium (IV) hydroxide, often called hydrous zirconia is an ill-defined material or family of materials variously described as and . All are white solids with low solubility in water. These materials are widely employed in the preparation of
solid acid catalyst
In acid catalysis and base catalysis, a chemical reaction is catalyzed by an acid or a base. By Brønsted–Lowry acid–base theory, the acid is the proton (hydrogen ion, H+) donor and the base is the proton acceptor. Typical reactions catalyzed ...

These materials are generated by mild base hydrolysis of
zirconium halide
In chemistry, a halide (rarely halogenide) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluor ...
s and nitrates. A typical precursor is
zirconium oxychloride
Zirconyl chloride is the inorganic compound with the formula of r4(OH)8(H2O)16l8(H2O)12, more commonly written ZrOCl2·8H2O, and referred to as zirconyl chloride octahydrate. It is a white solid and is the most common water-soluble derivative of ...
