Yttrium(III) nitrate is an inorganic compound, a salt with the formula Y(NO₃)₃. The hexahydrate is the most common form commercially available.

Preparation

Yttrium(III) nitrate can be prepared by dissolving corresponding metal oxide in 6 mol/L

nitric acid Nitric acid is the inorganic compound with the formula . It is a highly corrosive mineral acid. The compound is colorless, but older samples tend to be yellow cast due to decomposition into oxides of nitrogen. Most commercially available nitri ...

Properties

Yttrium(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO₃ is formed. At 600 C, the thermal decomposition is complete. Y₂O₃ is the final product. Y(NO₃)₃·3TBP is formed when tributyl phosphate is used as the extracting solvent.

Uses

Yttrium(III) nitrate is mainly used as a source of Y³⁺ cations. It is a precursor of some yttrium-containing materials, such as Y₄Al₂O₉, YBa₂Cu₃O_6.5+x and yttrium-based metal-organic frameworks. It can also be used as a catalyst in organic synthesis.
