'''Scandium(III) nitrate''', Sc(NO<sub>3</sub>)<sub>3</sub>, is an ionic compound. It is an oxidizer, as all nitrates are. '''Scandium(III) nitrate''', Sc(NO<sub>3</sub>)<sub>3</sub>, is an ionic compound. It is an ], as all ] are. The salt is applied in optical coatings, catalysts, electronic ceramics and the laser industry.

The tri- and tetrahydrate exist in the ]. Upon heating in air to 50&nbsp;°C, the tetrahydrate transforms into the dihydrate, which at 60&nbsp;°C further converts to Sc<sub>4</sub>O<sub>3</sub>(NO<sub>3</sub>)<sub>3</sub>·6.5H<sub>2</sub>O. At 140–220&nbsp;°C, Sc<sub>4</sub>O<sub>5</sub>(NO<sub>3</sub>)<sub>3</sub> is formed.<ref name=":0" />

Scandium nitrate has been found to form clusters when in an aqueous solution which can affect its behavior and properties in various ways. Small Angle neutron scattering<ref>{{Cite journal |last1=Karavaev |first1=I. A. |last2=Savinkina |first2=E. V. |last3=Grigor’ev |first3=M. S. |last4=Buzanov |first4=G.

This number depends on the concentration of the original scandium nitrate in the solution.

== Applications ==
Scandium nitrate has been found to be a successful catalyst in chemical reactions such as Beckmann rearrangement of ketoximes to amides<ref>{{Cite journal |last1=Sekine |first1=Tatsuya |last2=Hasegawa |first2=Yuko |date=February 1966 |title=Studies of Scandium in Various Solutions. I.

The catalytic success of scandium nitrate can be increased by modifying its structure in ways such as adding a co catalyst. Scandium nitrate is also the precursor for the synthesis of other scandium based compounds such as scandium oxide or scandium hydroxide. Scandium nitrate has also been investigated for its potential in luminescent materials due to its ability to strongly emit in the blue region of the spectrum.
