Zirconium (IV) hydroxide is an inorganic chemical compound of zirconium from the group of hydroxides .

Extraction and presentation

Zirconium (IV) hydroxide can be obtained by reacting acidic zirconium salt solutions with ammonia .

properties

Zirconium (IV) hydroxide is a white gelatinous solid that is practically insoluble in water. The case of ammonia addition to zirconium initially precipitated Tetrahydroxid hydrate is structurally a Zr 4 (OH) 8 (OH) 8 (H 2 O) 8 . By aging it goes into ZrO (OH) 2 • aq, by heating in the ZrO 2 over . According to the literature, there is no real tetrahydroxide, but it is a ZrO 2 x H 2 O, the water content of which changes.

use

Zirconium (IV) hydroxide can be used to make Friedel-Crafts catalysts. It is also an important intermediate in the production of zirconium.
