Yttrium(III) nitrate explained

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:[1]

Properties

Yttrium(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO3 is formed.[2] At 600 C, the thermal decomposition is complete. Y2O3 is the final product.[3]

Y(NO3)3·3TBP is formed when tributyl phosphate is used as the extracting solvent.[4]

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, YBa2Cu3O6.5+x and yttrium-based metal-organic frameworks.[5] It can also be used as a catalyst in organic synthesis.[6]
