Description and Uses

Zirconium hydroxide, often called hydrous zirconia is a water-insoluble, slightly alkaline amphoteric oxide, which is widely used in the preparation of pigments, glass, dyes and other industries, and is also an important intermediate for the preparation of other zirconium compounds.

Zirconium hydroxide is used in the pigment, dye, and glass colorants. The compound also is used to prepare zirconium oxide, sulfate, phosphate, and other salts.
