Chemical compound

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:

Y₂O₃ + 6 HNO₃ → 2 Y(NO₃)₃ + 3 H₂O

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 Y 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.
